sustainable energy is the key issue for the environment protection,human activity and economic development.Ionic liquids(ILs)and deep eutectic solvents(DESs)are dogmatically regarded as green and sustainable electrolytes in lithium-ion,lithium-metal(e.g.,lithium-sulphur,lithium-oxygen)and post-lithium-ion(e.g.,sodium-ion,magnesium-ion,and aluminum-ion)batteries.High electrochemical stability of ILs/DESs is one of the prerequisites for green,sustainable and safe energy;while easy electrochemical decomposition of ILs/DESs would be contradictory to the concept of green chemistry by adding the cost,releasing volatile/hazardous by-products and hindering the recyclability.However,(1)are ILs/DESs-based electrolytes really electrochemically stable when they are not used in batteries?(2)are ILs/DESs-based electrolytes really electrochemically stable in real batteries?(3)how to design ILs/DESs-based electrolytes with high electrochemical stability for batteries to achieve sustainability and green development?Up to now,there is no summary on this topic,to the best of our knowledge.Here,we review the effect of chemical structure and non-structural factors on the electrochemical stability of ILs/DESs in simulated conditions.More importantly,electrochemical stability of ILs/DESs in real lithium-ion,lithium-metal and post-lithium-ion batteries is concluded and compared.Finally,the strategies to improve the electrochemical stability of ILs/DESs in lithium-ion,lithium-metal and post-lithium-ion batteries are proposed.This review would provide a guide to design ILs/DESs with high electrochemical stability for lithium-ion,lithium-metal and postlithium-ion batteries to achieve sustainable and green energy.

Solar-driven cross-coupling reactions by dual nickel/photocatalysis under mild conditions have received considerable attention.However,the existing photo/nickel dual catalytic cross-coupling reactions require the addition of expensive photosensitizers and organic ligands,and the catalytic activity is inadequate.Herein,we report a nickel single-atom heterogeneous catalyst supported on mesoporous carbon nitride for photocatalytic C—O coupling reaction between 4-bromobenzonitrile and ethanol,affording 4-ethoxybenzonitrile in excellent yield compared to a semi-heterogeneous catalytic system.The catalytic system exhibits a broad substrate scope including ketones,aldehydes,esters,and amides.This work presents a simple and cost-effective strategy for anchoring metal single atoms onto carbon nitride,providing a new platform for enabling high-performance photocatalytic production of aryl ether compounds.

Since the discovery of mesoporous silica in 1990s,there have been numerous mesoporous silica-based nanomaterials developed for catalytic applications,aiming at enhanced catalytic activity and stability.Recently,there have also been considerable interests in endowing them with hierarchical porosities to overcome the diffusional limitation for those with long unimodal channels.Present processes of making mesoporous silica largely rely on chemical sources which are relatively expensive and impose environmental concerns on their processes.In this regard,it is desirable to develop hierarchical silica supports from natural minerals.Herein,we present a series of work on surface reconstruction,modification,and functionalization to produce diatomite-based catalysts with original morphology and macro-meso-micro porosities and to test their suitability as catalyst supports for both liquid-and gas-phase reactions.Two wet-chemical routes were developed to introduce mesoporosity to both amorphous and crystalline diatomites.Importantly,we have used computational modeling to affirm that the diatomite morphology can improve catalytic performance based on fluid dynamics simulations.Thus,one could obtain this type of catalysts from numerous natural diatoms that have inherently intricate morphologies and shapes in micrometer scale.In principle,such catalytic nanocomposites acting as miniaturized industrial catalysts could be employed in microfluidic reactors for process intensification.

^(13)C-Carbon is the most available source of carbon-13.It is a relatively inexpensive solid material,which can be easily converted to calcium carbide-^(13)C_(2).In current work,Ca^(13)C_(2)was used for in situ generation of^(13)C_(2)-acetylene in 1,3-dipolar cycloaddition and[4+2]cycloaddition reaction.For the first time,1H-1,2,3-triazoles-4,5-^(13)C_(2)and isoxazoles-4,5-^(13)C_(2)were synthesized using calcium carbide-^(13)C_(2).A Diels-Alder type cycloaddition of 3,6-di(pyridin-2-yl)-1,2,4,5-tetrazine and Ca^(13)C_(2)was investigated,and the best way for the synthesis of 3,6-di(pyridin-2-yl)pyridazine-4,5-^(13)C_(2)was proposed for the first time.Here we perform a detailled description of NMR spectra of^(13)C_(2)-labeled triazoles,isoxazoles and 3,6-di(pyridin-2-yl)pyridazine.

Comprehensive Summary,Although polyimides(PIs)have shown great potential for a broad range of applications,it remains very challenging to achieve the malleability,rehealability and recyclability for PIs and their composites targeting various applications,particularly for the rapidly emerging flexible and stretchable electronics.Herein,malleable conductive poly(imide-imine)hybrid(PIIH)vitrimer-graphene aerogel(GA)composites have been prepared,for the first time,via simple sol-gel film formation followed by heat-press.The resulting PIIH-GA composites exhibit not only the highly desired properties of thermosetting(strong mechanical strength)and thermoplastic(reprocessability)polymers,but also good conductivity enabled by the GA filler.PIIH3-GA-10(with 10 wt%GA)showed one of the highest electrical conductivities(26.7 S/m)for PI-based composites,as well as good electromagnetic interference(EMI)shielding performance.Moreover,the PIIH-GA films could maintain good performance during stretching and even after chemical recycling,which opens new opportunities for flexible and sustainable electronics development.

The rapid development of communication technology and electronic industry has brought unprecedented serious electromagnetic interference(EMI)and electromagnetic wave(EMW)pollution.Although EMI shields and EMW absorbers based on metal or magnetic materials were used to solve these problems,they have long been criticized for their high price,high density and easy corrosion.In order to achieve low density and efficient dissipation of electromagnetic energy,aerogels stand out among manifold materials.However,constructing aerogels with good EMI shielding or EMW absorption performance and acceptable mechanical properties is not an easy task.Burgeoning biopolymers,such as cellulose,lignin,chitin/chitosan and alginate,breathe new life into aerogels for high-efficiency EMW shielding and absorbing.Here,we reviewed the contributions of biopolymers in the fields of aerogels for EMW shielding and absorbing.At the same time,some challenges and outlook were also pointed out,aiming to promote the advance of aerogel-based EMI shields and EMW absorbers as well as the rational utilization of biopolymers.

Comprehensive Summary Carbon nanodots(CDs)with high photothermal performance are ideal candidates for tumor photothermal therapy(PTT).Herein,we investigated the photothermal performance of CDs synthesized from urea and citric acid via solvothermal method in dimethyl sulfoxide(DMSO)at different temperatures.Photothermal conversion efficiency(PCE)of up to 61.3%was obtained in the CDs synthesized at 150℃(150-CDs),which is much better than the CDs synthesized at 180℃(180-CDs).By analyzing the morphologies,chemical structures,and absorption spectra of these CDs,we found that the photothermal effect of the CDs was due to the lattice vibration of their carbonized cores.

Chinese Journal of chemistry 2023年第21期41卷 2908-2924页

作者： Xuwen Zhang Yibo Shi Yunfeng Deng Yanhou Geng School of Materials Science and Engineering and Tianjin Key Laboratory of Molecular Optoelectronic Science Tianjin Universityand Collaborative Innovation Center of Chemical Science and Engineering(Tianjin)Tianjin300072 China Joint School of National University of Singapore and Tianjin University International Campus of Tianjin UniversityBinhai New CityFuzhouFujian350207 China

Direct arylation polycondensation(DArP)has emerged as an eco-friendly and atom-efficient methodology for the syntheses ofπ-conjugated polymers(CPs).This approach features the direct C—H arylation of an aromatic hydrocarbon with an aryl halide.Given the prevalence of thiophene-containing CPs,achieving efficient and defect-free DArP of thiophene-based C−H monomers is of great significance.This review presents a mechanistic insight into DArP and describes the development of DArP catalytic systems for varied thiophene-based C−H monomers.Moreover,the control of the primary defects(i.e.,branching and homo-coupling)in thiophene-based DArP is also elaborated.By emphasizing the principles behind monomer selection and catalytic system optimization,this review intends to provide a framework for future advancements in the DArP of thiophene-containing CPs.

CO_(2)-Free Calcium Carbide Manufacturing: Demanded Strategy in the Carbon-Neutral Chemical Industry

引用

Chinese Journal of chemistry 2023年第24期41卷 3611-3617页

作者： Dmitriy E.Samoylenko Konstantin S.Rodygin Valentine P.Ananikov Institute of chemistry Saint Petersburg State University7/9 Universitetskaya nabSt.Petersburg199034 Russia Zelinsky Institute of Organic chemistry Russian Academy of SciencesLeninsky pr.47Moscow119991 Russia

Calcium carbide is considered a possible key component in the sustainable carbon cycle,including convenient recycling of carbon wastes to industrial uptake.However,currently employed CaC2 manufacturing process produces significant amounts of CO_(2).One of the main factors of its appearance is the formation of carbon oxide during the reaction.The reaction of lime ore with coal inevitably results in the formation of CO and the loss of one carbon atom.CO is usually burnt,forming CO_(2) to maintain the required high temperature during synthesis – 2200 ℃.In the present study,we discuss that the use of calcium metal instead of lime represents a good opportunity to prevent CO_(2) emission since the reaction of Ca with carbon occurs in an atom-efficient manner and results in only CaC_(2) at a much lower temperature of 1100 ℃.Here,the reaction of Ca with carbon was successfully tested to synthesize CaC_(2).The desired product was isolated in gram-scale amounts in 97.2% yield and 99% purity.The environmental friendliness of the proposed method originates from the calculations of the E-factor.Rationalization is provided concerning the cost factor of Ca within the considered process.
