    Double-layered skeleton of Li alloy anchored on 3D metal foam enabling ultralong lifespan of Li anode under high rate

    Bi3+-activated dual-wavelength emitting phosphors toward effective optical thermometry

    查看更多>>摘要：Optical thermometry as an important local temperature-sensing technique,has received increasing atten-tion in scientific and industrial areas.However,it is still a big challenge to develop luminescent materi-als with self-activated dual-wavelength emissions toward high-sensitivity optical thermometers.Herein,a novel ratiometric thermometric strategy of Bi3+-activated dual-wavelength emission band was real-ized in the same lattice position with two local electronic states of La3Sb1-xTaxO7:Bi3+(0≤x≤ 1.0)ma-terials based on the different temperature-dependent emission behaviors,benefiting from the highly-sensitive and regulable emission to the coordination environment of Bi3+.The structural and spectral results demonstrate that the emission tremendously shifted from green to blue with 68 nm and the in-tensity was enhanced 2.6 times.Especially,the visual dual-wavelength emitting from two emission cen-ters was presented by increasing the Ta5+substitution concentration to 20％or 25％,mainly originating from the two local electronic states around the Bi3+emission center.Significantly,the dual-wavelength with different thermal-quenching performance provided high-temperature sensitivity and good discrim-ination signals for optical thermometry in the range between 303 and 493 K.The maximum rela-tive sensitivity reached 2.64％/K(La3Sb0.8Ta0.2O7:0.04Bi3+@383 K)and 1.91％/K(La3Sb0.75Ta0.25O7:0.04Bi3+@388 K).This work reveals a rational design strategy of different local electronic states around the single-doping multiple emission centers towards practical applications,such as luminescence thermometry and white LED lighting.

    S1-supported Pd@CeO2 quasi-core@shell materials as advanced catalysts for selective hydrogenation of furfural

    Xiang ChuLingling ZhangKe WangRui Zhang...
    493-496页
    查看更多>>摘要：Bare Pd metal nanoparticles invariably suffer from poor selectivity in furfural hydrogenation by forming flat configurations,with the aromatic ring of the substrate molecules parallel to the metal surface.Herein,we put forward a promising solution by using CeO2 as promoters to modify Pd nanoparticles for modu-lating the adsorption behaviors of furfural molecules.To achieve the highly-desired ultra-small Pd@CeO2 core@shell nanostructure,a"constrained auto-redox"synthesis is developed,in which silicalite-1 sup-ports play the key role of providing their surface as the landing place of PdOx precursors for inhibiting the overgrowth and the deformation.To the best of our knowledge,this is one of the smallest core@shell materials obtained from aqueous synthesis.When evaluated as catalysts,Pd@CeO2/S-1 gives 98.9％con-version of furfural with 94.3％selectivity for furfural alcohol in 15 h,which is much better than that of Pd/S-1(88.6％conversion with 44.3％selectively).The DFT simulation reveals a strong interaction between the defects of CeO2 and the oxygen atom of the-CHO group in furfural molecules,which benefits the selective hydrogenation occurred in the-CHO group rather than the furan ring.

    查看更多>>摘要：Highly efficient catalysts for electrolysis of water are crucial to the development of hydrogen energy which is helpful to carbon neutralization.Recently,high temperature shock(HTS),with advantage of rapid speed,universality and scalable production,has been a promising method in synthesis of nanomaterials.In this paper,HST was used to treat low Pt loading Mo6S8 for enhanced water splitting performance.Im-pressively,the optimized MoS2/MoO2/Mo6S8 nano-composite with low Pt mass loading(～4％)displays well hydrogen evolution reaction(HER)electrochemical performance.The overpotential is 124 mV to reach 10mA/cm2 and the corresponding Tafel slope is 88mV/dec in acidic electrolyte.Its mass activity is 6.2mA/μgpt at-124 mV vs.RHE,which is almost 2 times relative to 20％Pt/C.Moreover,it presents distinguished stability even after 2000 cycles.This work will broaden the way of catalysts preparation and the application of hydrogen evolution.

    Organic interfacial engineering of gold nanowires for selective glycerol electrooxidation

    Zhe WangQingling HongBoqiang MiaoTianjiao Wang...
    502-507页
    查看更多>>摘要：The selective electrochemical conversion of glycerol into value-added products is a green and sus-tainable strategy for the biomass utilization.In this work,Au nanowires(Au-NW)modified with polyethyleneimine(PEI)molecule(Au-NW@PEI)is obtained by an up-bottom post-modification approach.Physical characterization,molecular dynamics simulation and density functional theory demonstrate that the loose-packed PEI monolayer firmly and uniformly distribute on the Au-NW surface due to the strong Au-N interaction.Electrochemical experiments and product analysis display that PEI modification signif-icantly enhance the electro-activity of Au-NW for the glycerol electro-oxidation reaction(GEOR)due to the electronic effect.Meanwhile,the steric hindrance and electrostatic effect of PEI layer make the op-timizing adsorption of intermediates possible.Therefore,the selectivity of C3 product glyceric acid over Au-NW@PEI is increased by nearly 20％.The work thus indicates that the rational design of metal-organic interface can effectively elevate the electro-activity and selectivity of Au nanostructures,which may have wide application in biomass development.

    查看更多>>摘要：Aluminosilicate small pore zeolites belonging to ABC-6 family play crucially important roles in the high methanol conversion with the high selectivity of light olefins,gas separation and storage,and selective catalytic reduction of NOx.In this work,we report a general method,called the epitaxial growth ap-proach,for designing ABC-6 family small pore zeolites.It is mainly realized through the epitaxial growth on the nonporous SOD-type zeolite in the presence of inorganic cations(Na+and K+)combined with a variety of organic structure directing agents(OSDAs).In this case,a series of ABC-6 family small pore zeolites such as ERI-,SWY-,LEV-,AFX-,and PTT-type zeolites have been successfully synthesized within a few hours.More importantly,the advanced focused ion beam(FIB)and the low-dose high-resolution transmission electron microscopy(HRTEM)imaging technique have been utilized for unraveling the ze-olite heterojunction at the atomic level during the epitaxial growth process.It turns out(222)crystallo-graphic planes of the SOD-type zeolite substrate provide unique pre-building units,which facilitate the growth of targeted ABC-6 family small pore zeolites along its c-axis.Moreover,the morphologies of ERI-type zeolite can also be tuned through the epitaxial growth approach,achieving a longer lifetime in the methanol conversion.

    查看更多>>摘要：Construction of proton transport channels in metal-organic frameworks(MOFs)with simple synthesis processes,high proton conductivities and good performance stabilities has been of great interest for pro-ton exchange membrane fuel cell(PEMFC).Herein,we mimic the proton transport behavior of amino acid residues in bacteriorhodopsin,select UiO-66-COOH as the host,glycine and aspartic acid as the func-tional guest molecules,and then functionalize the MOF framework with amino acids to obtain biomimetic proton transport channels.This strategy endows UiO-66-COOH-Asp a high proton conductivity of 1.19 x 10-2 S/cm at 70 ℃ and 98％RH,excellent cycle stability of performances and performance durability,which can be comparable to the reported MOFs-based proton conductors.Moreover,the proton conduc-tion mechanism in UiO-66-COOH-Asp is elaborated in detail due to its visual structure,which is also one of the advantages of adopting MOFs as research platform,making it possible to optimize the structure-activity relationship of advanced materials.Notably,this strategy has clear objectives and simple synthe-sis,which has made certain contributions to both theoretical research and future industrial production of proton conductors.

    518-522页
    查看更多>>摘要：The controllable morphology and composition of catalysts are crucial to improving the electrocatalytic activity of oxygen evolution reaction(OER).Herein,we construct a bimetallic heterostructure by sulfi-dation and hydrothermal methods,and the layered ReS2 is vertically aligned on Prussian blue-derived hollow Co9S8 nanocubes(Co9S8@ReS2).The core-shell structure of Co9S8@ReS2 can effectively prevent the restacking of layered ReS2,expose the abundant surface area and improve the utilization of electro-catalytic sites,resulting in fast electrolyte diffusion and charge transfer during OER.Due to the synergistic effect of the core-shell morphology and the formed bimetallic heterostructure,Co9S8@ReS2 exhibits ex-cellent catalytic OER performance.At 10mA/cm2,only 288 mV of overpotential is required with the Tafel slope of 73.3mV/dec for Co9S8@ReS2,which are both lower than that of Co9S8 and ReS2.Meanwhile,Co9S8@ReS2 exhibits high catalytic stability and low charge transfer resistance and the boosted active sites are confirmed by density functional theory.This work provides a rational design of the OER cata-lysts by constructing the bimetallic heterostructure.

    523-527页
    查看更多>>摘要：The intricate correlation between multiple degrees of freedom and physical properties is a fascinating area in solid state chemistry and condensed matter physics.Here,we report a quantum-magnetic system BaNi2V2O8(BNVO),in which the spin correlation was modulated by unusual oxidation state,leading to different magnetic behavior.The BNVO was modified with topochemical reduction(TR)to yield TR-BNVO with partially reduced valance state of Ni+in the two-dimensional NiO6-honeycomb lattice.Accordingly,the antiferromagnetic order is suppressed by the introduction of locally interposed Ni+and oxygen va-cancies,resulting in a ferromagnetic ground state with the transition temperature up to 710 K.A posi-tive magnetoresistance(7.5％)was observed in the TR-BNVO at 40 K under 7 T.These findings show that topological reduction is a powerful approach to engineer low-dimensional materials and accelerate the discovery of new quantum magnetism.

    查看更多>>摘要：Two 3d-4f-5d heterometallic cluster-containing polyoxometalates,formulated as Na22{(SbW9O33)4[La3W6MO18(H2O)8(CH3COO)4]2}.nH2O(abbreviated as La6M2,M=Co/Mn)were synthesized and struc-turally characterized.Single-crystal X-ray diffraction analyses reveal that the polyanions of La6Co2 and La6Mn2 consist of the uncommon 3d-4f-5d clusters {La6W12Co2} and {La6W12Mn2},which are encapsu-lated by four trilacunary Keggin tungstoantimonates to form the parallelogram-shaped title compounds.Additionally,the polyanions can be extended into a two-dimensional(2D)frame by the linkage of periph-eral Na+ions.The inner space of the 2D layer was filled with water molecules and thus an H-bonded network was formed,which is expected to exhibit a fascinating proton conductivity.The study of water-assisted proton conduction demonstrated that La6Co2 and La6Mn2 were temperature-and humidity-dependent proton conductors,respectively,and the proton conductivities could reach 1.3 × 10-2 and 2.3 × 10-2 S/cm at 65 ℃ and 90％RH conditions.
