    Ionic liquid-assisted preparation of hydroxyapatite and its catalytic performance for decarboxylation of itaconic acid

    Shutong PangHualiang AnXinqiang ZhaoYanji Wang...
    9-15页
    查看更多>>摘要：The synthesis of methacrylic acid from biomass-derived itaconic acid is a green route,for it can get rid of the dependence on fossil resource.In order to solve the problems on this route such as use of a precious-metal catalyst and a corrosive homogeneous alkali,we prepared a series of hydroxyapatite catalysts by an ionic liquid-assisted hydrothermal method and evaluated their catalytic performance.The results showed that the ionic liquid[Bmim]BF4 can affect the crystal growth of hydroxyapatite,provide fluoride ion for fluorination of hydroxyapatite,and adjust the surface acidity and basicity,morphology,textural properties,crystallinity,and composition of hydroxyapatite.The[Bmim]BF4 dosage and hydrothermal temperature can affect the fluoride ion concentration in the hydrothermal system,thus changing the degree of fluoridation of hydroxyapatite.High fluoride-ion concentration can lead to the formation of CaF2 and thus significantly decrease the catalytic performance of hydroxyapatite.The hydrothermal time mainly affects the growth of hydroxyapatite crystals on the c axis,leading to different catalytic perfor-mance.The suitable conditions for the preparation of this fluoridized hydroxyapatite are as follows:a mass ratio of[Bmim]BF4 to calcium salt=0.2∶1,a hydrothermal time of 12 h,and a hydrothermal temperature of 130 ℃.A maximal methacrylic acid yield of 54.7％was obtained using the fluoridized hydroxyapatite under relatively mild reaction conditions(250 ℃ and 2 MPa of N2)in the absence of a precious-metal catalyst and a corrosive homogeneous alkali.

    Effect of mesopore spatial distribution of HZSM-5 catalyst on zinc state and product distribution in 1-hexene aromatization

    16-26页
    查看更多>>摘要：1-hexene aromatization is a promising technology to convert excess olefin in fluid catalytic cracking(FCC)gasoline to high-value benzene(B),toluene(T),and xylene.Besides,the increasing market demand of xylene has put forward higher requirements for new generation of catalyst.For increasing xylene yield in 1-hexene aromatization,the effect of mesopore structure and spatial distribution on product distri-bution and Zn loading was studied.Catalysts with different mesopore spatial distribution were prepared by post-treatment of parent HZSM-5 zeolite,including NaOH treatment,tetra-propylammonium hy-droxide(TPAOH)treatment,and recrystallization.It was found the evenly distributed mesopore mainly prolongs the catalyst lifetime by enhancing diffusion properties but reduces the aromatics selectivity,as a result of damage of micropores close to the catalyst surface.While the selectivity of high-value xylene can be highly promoted when the mesopore is mainly distributed interior the catalyst.Besides,the state of loaded Zn was also affected by mesopores spatial distribution.On the optimized catalyst,the xylene selectivity was enhanced by 12.4％compared with conventional Zn-loaded parent HZSM-5 catalyst at conversion over 99％.It was attributed to the synergy effect of mesopores spatial distribution and optimized acid properties.This work reveals the role of mesopores in different spatial positions of 1-hexene aromatization catalysts in the reaction process and the influence on metal distribution,as well as their synergistic effect two on the improvement of xylene selectivity,which can improve our un-derstanding of catalyst pore structure and be helpful for the rational design of high-efficient catalyst.

    27-38页
    查看更多>>摘要：A series of adsorbent materials(WPU-HAx-y)with a three-dimensional porous structure,green sus-tainability,and excellent performance were prepared and evaluated for the removal of methylene blue using nontoxic and environmentally friendly waterborne polyurethane as the matrix material and humic acid,a biomass material,as the functional material.The newly synthesized adsorbents were character-ized by infrared spectroscopy,scanning electron microscopy,specific surface area,and thermogravi-metric.The effects of contact time(0-8 h),starting concentration(10-100 mg·L-1),pH(3-11),solution temperature(30-60 ℃),and coexisting ions(Ca2+,Na+,K+,Mg2+)on the performance were investi-gated.Pseudo-first-order,pseudo-second-order,elovich,and intra-particle diffusion models were used to analyze the adsorption kinetics;the Langmuir,Freundlich,Temkin,and Dubin-Radushkovich adsorption isotherms were evaluated;and the adsorption behavior of the adsorbent materials was found to be more appropriate for the pseudo-second-order model for chemical pollutant removal than the Langmuir model,which depends on monolayer adsorption.WPU-HA2-3 stood out with a maximum adsorption capacity of 813.0081 mg·g-1 fitted to the pseudo-second-order and 309.2832 mg·g-1 fitted to the Langmuir model,showing superior adsorption performance and regenerability.

    39-48页
    查看更多>>摘要：High-energy-density fuels are important for volume-limited aerospace vehicles,but the increase in fuel energy density always leads to poor cryogenic performance.Herein,we investigated the transposed Paternò-Büchi reaction of biomass cyclic ketone and cyclic alkene to synthesize a new kind of alkyl-substituted polycyclic hydrocarbon fuel with high energy density and good cryogenic performance.The triplet-energy-quenching results and phosphorescent emission spectra reveal the sensitization mechanism of the reaction,including photosensitizer excitation,triplet-triplet energy transfer,cyclization,and relaxation,and the possible reaction path was revealed by the density functional theory(DFT)calculations.The reaction conditions of photosensitizer type and addition,molar ratio of substrates,reaction temperature,and incident light intensity were opti-mized,with the target product yield achieving 65.5％.Moreover,the reaction dynamics of the re-action rate versus the light intensity are established.After the hydrogenation-deoxygenation reaction,three fuels with a high density of 0.864-0.938 g·ml-1 and a low freezing point of＜-55 ℃ are obtained.This work provides a benign and effective approach to synthesize high-performance fuels.

    Alleviation of the plastic deformation of gel ink under strong stress through an esterification of xanthan gum reinforcing its double helix structure

    Xiaokun LiMingyi WangZilu LiuSong Yang...
    49-57页
    查看更多>>摘要：As a natural organic polymer,xanthan gum(XG)can alleviate the plastic deformation of gel ink under strong stress and realize the reasonable regulation of the rheological properties of gel ink.However,as the double-helix structure connected by hydrogen bonds cannot resist the mechanical environment of strong stress,XG shows poor shear resistance.In this study,a polymer gel with interpenetrating polymer network structure was prepared by esterifying XG,taking polystyrene maleic anhydride(SMA)as the modifier.In addition to retaining the excellent rheological properties of XG,the generated polymer gel also exhibited high shear resistance.The optimal addition amount of the esterification reaction modifier was determined as mxc∶msMA=5∶3 according to the gel ink standard.With this amount,the viscosity of the modified xanthan gum(SXG)gel increased to 1578.8 mPa·s and 100.7 mPa·s at shear rates of 4 s-1 and 383 s-1,respectively,and the shear resistance increased more than 2 times compared to the un-modified one.It is because of the ester bond formed by esterification that the reaction strengthens the interaction between molecular segments,enabling the new gel to resist to strong mechanical stress.The new polymer gel studied in this paper and the proposed mechanism of action provide new insights for the development of high-end gel ink and also provide theoretical support for the study of rheological properties of non-Newtonian fluids.

    58-67页
    查看更多>>摘要：The sluggish redox kinetics of polysulfides in lithium-sulfur(Li-S)batteries are a significant obstacle to their widespread adoption as energy storage devices.However,recent studies have shown that tungsten oxide(WO3)can facilitate the conversion kinetics of polysulfides in Li-S batteries.Herein,we fabricated host materials for sulfur using nitrogen-doped carbon nanotubes(N-CNTs)and WO3.We used low-cost components and simple procedures to overcome the poor electrical conductivity that is a disadvantage of metal oxides.The composites of WO3 and N-CNTs(WO3/N-CNTs)create a stable framework structure,fast ion diffusion channels,and a 3D electron transport network during electrochemical reaction pro-cesses.As a result,the WO3/N-CNT-Li2S6 cathode demonstrates high initial capacity(1162 mA·h·g-1 at 0.5 C),excellent rate performance(618 mA·h·g-1 at 5.5 C),and a low capacity decay rate(0.093％up to 600 cycles at 2 C).This work presents a novel approach for preparing tungsten oxide/carbon composite catalysts that facilitate the redox kinetics of polysulfide conversion.

    68-77页
    查看更多>>摘要：For the reduction of bovine serum proteins from wastewater,a novel mixed matrix membrane was prepared by functionalizing the substrate material polyaryletherketone(PAEK),followed by carboxyl groups(C-SPAEKS),and then adding amino-functionalized UiO-66-NH2(Am-UiO-66-NH2).Amino-functionalization of UiO-66 was accomplished by melamine,followed by an amidation reaction to immobilize Am-UiO-66-NH2,which was immobilized on the surface of the membrane as well as in the pore channels,which enhanced the hydrophilicity of the membrane surface while increasing the negative potential of the membrane surface.This nanoparticle-loaded ultrafiltration membrane has good permeation performance,with a pure water flux of up to 482.3 L·m-2·h-1 for C-SPAEKS/Am-UiO-66-NH2 and a retention rate of up to 98.7％for bovine serum albumin(BSA)-contaminated so-lutions.Meanwhile,after several hydrophilic modifications,the flux recovery of BSA contaminants by this series of membranes increased from 56.2％to 80.55％of pure membranes.The results of ultra-filtration flux time tests performed at room temperature showed that the series of ultrafiltration membranes remained relatively stable over a test time of 300 min.Thus,the newly developed mixed matrix membrane showed potential for high efficiency and stability in wastewater treatment con-taining bovine serum proteins.

    查看更多>>摘要：To address the low conductivity and easy agglomeration of transition metal sulfide nanoparticles,FeCoS4 nanoparticles embedded in S-doped hollow carbon(FeCoS4@S-HC)composites were successfully fabri-cated through a combination of hydrothermal processes and sulfidation treatment.The unique bowl-shaped FeCoS4/S-HC composites exhibit excellent structural stability with a high specific surface area of 303.7 m2·g-1 and a pore volume of 0.93 cm3·g-1.When applied as anode material for lithium-ion batteries,the FeCoS4@S-HC anode exhibits efficient lithium storage with high reversible specific ca-pacity(970.2 mA·h·g-1 at 100 mA·g-1)and enhanced cycling stability(574 mA·h·g-1 at 0.2 A·g-1 after 350 cycles,a capacity retention of 84％).The excellent lithium storage is attributed to the fact that the bimetallic FeCoS4 nanoparticles with abundant active sites can accelerate the electrochemical reaction kinetics,and the bowl-shaped S-HC structure can provide a stable mechanical structure to suppress volume expansion.

    查看更多>>摘要：The use of fillers to enhance the corrosion protection of epoxy resins has been widely applied.In this work,cerium dioxide(CeO2)and benzotriazole(BTA)were introduced into an epoxy resin to enhance the corrosion resistance of Q235 carbon steel.Scanning electron microscopy results indicated that the CeO2 grains were rod-like and ellipsoidal in shape,and the distribution pattern of BTA was analyzed by energy dispersive spectroscope.The dynamic potential polarization curve proved the excellent corrosion resistance of the composite epoxy resin with CeO2 and BTA co-addition,and electrochemical impedance spectroscopy test analysis indicated the significantly enhanced long-term corrosion protection perfor-mance of the composite coating.And the optimal protective performance was provided by the coating containing 0.3％(mass)CeO2 and 20％(mass)BTA,which was attributed to the barrier performance of CeO2 particles and the chemical barrier effect of BTA.The formation of corrosion products was analyzed using X-ray diffraction.In addition,the corrosion resistance mechanism of the coating was also discussed in detail.
