    100-106页
    查看更多>>摘要：Due to their superior fluorescence,phosphorescence,and catalytic capabilities,carbon dots(CDs),an emerging class of fluorescent carbon nanomaterials,have a wide range of potential applications.The properties of CDs have recently been controlled extensively by heteroatom doping.Boron atoms have been effectively doped into the structure of CDs due to their similar size to carbon atoms and excellent electron-absorbing ability to further improve the performance of CDs.In this review,we summarize the research progress of boron-doped CDs in recent years from the aspects of doping strategies,effects of boron doping on different performances of CDs and applications.Starting from the two aspects of sin-gle boron doping and boron and other atom co-doping,from different precursor materials to different synthesis methods,the doping strategies of boron-doped CDs are reviewed in detail.Then,the effects of boron doping on the fluorescence,phosphorescence and catalytic performance of CDs and applications of boron-doped CDs in optical sensors,information encryption and anti-counterfeiting are discussed.Finally,we further provide a prospect towards the future development of boron-doped CDs.

    107-120页
    查看更多>>摘要：In recent years,rechargeable zinc-ion batteries(ZIBs)are considered to be a promising alternative to lithium-ion batteries owing to their high safety and theoretical capacity with low cost.Nevertheless,the in-depth development of rechargeable zinc-ion batteries is restricted by a sequence of issues,such as the dissolution and structure collapse of cathode materials,the formation of by-products,severe anode cor-rosion,passivation,and the growth of zinc dendrites.The covalent organic frameworks(COFs)can solve the above problems to a certain extent owing to their ideal characteristics,such as rigid structure,in-solubility,high porosity,and abundant active sites.COFs,as advanced materials for ZIBs,have attracted researchers'attention.In this review,we systematically summarized the synthesis methods of COFs and discussed the application of several advanced characterization technologies in COFs,which would provide a reference for the in-depth research of COFs.In addition,we elucidated the use of COFs as cathode ma-terials and anode protective layers in rechargeable ZIBs.Finally,we discussed the challenges and solutions in the development of COF materials,which would provide constructive insights into the future direction of COFs.

    Effect of electrolyte cation-mediated mechanism on electrocatalytic carbon dioxide reduction

    Yuan DongMutian MaZhenyang JiaoSheng Han...
    139-146页
    查看更多>>摘要：The steep reduction in costs and systematic optimization of renewable electricity has ignited an intensi-fying interest in harnessing electroreduction of carbon dioxide(CO2RR)for the generation of chemicals and fuels.The focus of research over the past few decades has been on the optimization of the electrode and the electrolyte environment.Notably,cation species in the latter have recently been found to dramat-ically alter the selectivity of CO2RR and even their catalytic activity by multiple orders of magnitude.As a result,the selection of cations is a critical factor in designing catalytic interfaces with high selectivity and efficiency for targeted products.Informed decision-making regarding cation selection relies on a compre-hensive understanding of prevailing electrolyte effect models that have been used to elucidate observed experimental trends.In this perspective,we review the hypotheses that explain how electrolyte cations influence CO2RR by mechanisms such as through tuning of the interfacial electric field,buffering of the local pH,stabilization of the key intermediates and regulation of the interfacial water.Our endeavor is to elucidate the molecular mechanisms underpinning cation effects,thus fostering the evolution of more holistic and universally applicable predictive models.In this regard,we highlight the current challenges in this area of research,while also identifying potential avenues for future investigations.

    查看更多>>摘要：Lithium-sulfur batteries(LSBs)boasting remarkable energy density have garnered significant attention within academic and industrial spheres.Nevertheless,the progression of LSBs remains constrained by the languid redox kinetics intrinsic to sulfur and the pronounced shuttle effect induced by lithium poly-sulfides(LiPSs),which seriously affecting the energy density,cycling life and rate capacity.The concep-tualization and implementation of catalytic materials stand acknowledged as a propitious stratagem for orchestrating kinetic modulation,particularly in excavating the conversion of LiPSs and has evolved into a focal point for disposing.Among them,chalcogenide catalytic materials(CCMs)have shown satisfactory catalytic effects ascribe to the unique physicochemical properties,and have been extensively developed in recent years.Considering the lack of systematic summary regarding the development of CCMs and corre-sponding performance optimization strategies,herein,we initiate a comprehensive review regarding the recent progress of CCMs for effective collaborative immobilization and accelerated transformation kinet-ics of LiPSs.Following that,the modulation strategies to improve the catalytic activity of CCMs are sum-marized,including structural engineering(morphology engineering,surface/interface engineering,crystal engineering)and electronic engineering(doping and vacancy,etc.).Finally,the application prospect of CCMs in LSBs is clarified,and some enlightenment is provided for the reasonable design of CCMs serving practical LSBs.

    167-172页
    查看更多>>摘要：The utilization of an efficient photocatalyst is crucial for the photocatalytic degradation of antibiotics in water through visible light,which is an imperative requirement for the remediation of water environ-ments.In this study,a novel Cu-CeO2/BiOBr Z-type heterojunction was synthesized by calcination and hydrothermal methods,and the degradation rate of sulfathiazole(STZ)antibiotic solution was studied using simulated illumination(300 W xenon lamp).The results indicated that 3％ Cu-CeO2/BiOBr achieved a degradation rate of 92.3％ within 90 min when treating 20 mg/L STZ solution,demonstrating its poten-tial for practical water treatment applications.Characterization using various chemical instruments re-vealed that 3％ Cu-CeO2/BiOBr exhibited the lowest electron-hole recombination rate and electron trans-fer resistance.Furthermore,the utilization of ESR data and quenching experiments has substantiated the involvement of hydroxyl radicals(·OH)and superoxide radicals(·O2-)as the primary active species.Con-sequently,a plausible degradation mechanism has been inferred.These findings offer a prospective ap-proach for the development of heterojunction materials with appropriate band matching.

    173-177页
    查看更多>>摘要：The preparation of hydrogel adsorbents with admirable performance for efficient selective remove Pb(Ⅱ)in complex wastewater still remains a great challenge.Herein,a novel bifunctional modified polymer hydrogel PAM-PAMPS was prepared by crosslinking acrylamide(AM)and 2-acrylamido-2-methylpropanesulfonic acid(AMPS).Compared with PEG,PAA and PAMPS,PAM-PAMPS exhibited both the maximum adsorption capacity of Pb(Ⅱ)(541.90mg/g)and satisfactory selectivity for Pb(Ⅱ)in mul-tiple heavy metal ions coexistence solutions.Various characterizations indicated that-SO3H and-NH2 as active sites on PAM-PAMPS occur the synergistic effects of ion-exchange and coordination with Pb(Ⅱ)during the adsorption process,respectively.The adsorption energy Ead(PAM-PAMPS)obtained from density functional theory(DFT)calculations was lower than the other three hydrogels,manifesting that PAM-PAMPS formed the most stable complex with Pb(Ⅱ),which further demonstrated that Pb(Ⅱ)preferred to combine with PAM-PAMPS to selective capture of Pb(Ⅱ).The practice utilization of PAM-PAMPS was as-sessed by wastewater of electroplate containing Pb(Ⅱ).Meanwhile,the removal ratio of PAM-PAMPS was maintained at about 89％ after 4 adsorption-desorption cycles.This study establishes a new and effective idea for the design and fabrication of bifunctionalized modified polymer hydrogels.

    Complexes of cupric ion and tartaric acid enhanced calcium peroxide Fenton-like reaction for metronidazole degradation

    Shiyu PanBo CaoDeling YuanTifeng Jiao...
    183-187页
    查看更多>>摘要：To surmount the obstacles of traditional Fenton method and synchronously utilize Cu2+ and polyphe-nol in water,an improved Fenton-like reaction applying calcium peroxide(CaO2)as H2O2 source and regulating by the complex of Cu2+-tartaric acid(TA,a representative of polyphenol)was constructed.A typical antibiotic,metronidazole(MTZ)could be effectively eliminated by the Cu2+/TA/CaO2 system,and the optimized parameters were as follows:0.1mmol/L Cu2+,2mmol/L TA,2mmol/L CaO2,and initial pH 5.UV spectrum confirmed the formation of Cu2+-TA complex,which promoted the Cu2+/Cu+ circulation through decreasing the Cu2+/Cu+ couple redox potential,which further enhanced the H2O2 decompo-sition and the formation of reactive species.Hydroxyl radical was dominant for MTZ degradation,fol-lowed by oxygen and superoxide radical.The degradation intermediates of MTZ were detected and their evolution way was speculated.Furthermore,the ternary process showed a wide pH tolerance(3-8)for removing MTZ and broad applicability for eliminating other dyes and antibiotics.This work provided a reference for Cu-based Fenton-like strategy for organic wastewater settlement.

    188-191页
    查看更多>>摘要：TiO2-based films are one of the most attractive photocatalysts owing to their highly cost-effective prop-erties.Nevertheless,most TiO2-based photocatalytic films for dye degradation are in the form of robust films(without flexibility),TiO2 coatings on carbon matrix(with leakage risk),or surface-covered TiO2 hy-brids(not favorite to contact with external molecules).Therefore,the development of durable and highly efficient TiO2 photocatalytic films for dye degradation is still needed.Here,we fabricated soft photocat-alytic hybrid membranes(TANFs)from TiO2 nanotubes(TiNT)and aramid nanofiber(ANF)by a facile vacuum filtration process.The similar morphology and dimension of TiNT and ANF enable them intri-cately intertwine with each other in the membrane network.Under an appropriate mixing ratio,the TANF exhibited significantly improved optical and mechanical properties.When used for dye degradation,the membrane showed excellent photocatalytic performance and could keep stable activity and integrated state for repeated usage.
