| 1 | Application of deep eutectic solvents in biomass pretreatment and conversion显示文摘Biomass is renewable, abundant, cheap, biocompatible, and biodegradable materials and has been used to produce chemicals, materials,energy, and fuels. However, most of the biomass, especially most of the biomass polymers are not soluble in common solvents, which hinders their pretreatment and conversion. Deep eutectic solvents(DESs) are environmental-friendly, cheap, and highly tunable, with high solubility,which renders them potential applications in biomass pretreatment and conversion. They could be used as solvents or catalysts and so on. This paper intends to review the application of DESs for the pretreatment of biomass and conversion of biomass to value-added products. We focus on the following topics related to biomass and DESs:(1) DESs for the pretreatment of biomass;(2) DESs for the dissolution and separation of biomass or extraction of chemicals from biomass;(3) DESs for biomass conversion;(4) Drawbacks, and recyclability of DESs for pretreatment and conversion of biomass. | Yu Chen Tiancheng Mu | 2019 | Green Energy & Environment2019，4，2： | 15 |
| 2 | Revisiting greenness of ionic liquids and deep eutectic solvents显示文摘Green solvents are one of the hot topics of green chemistry.Ionic liquids(ILs)and deep eutectic solvents(DESs)are deemed as green solvents to a certain extent,and they have been applied in many areas,such as dissolution,separation,catalysis,electrochemistry and material synthesis.However,the greenness of ILs and DESs should be revisited because more and more evidences have shown that they are not always green.In this perspective,besides the reported merits,the disadvantages and problems of some ILs and DESs,such as instability,volatility,hygroscopicity,toxicity,flammability,regenerability,cost,energy consumption and impurities are discussed.Moreover,13 strategies to avoid the disadvantages of ILs and DESs and to increase the greenness are proposed.Comparison of the greenness of ILs and DESs is further conducted.This perspective provides some new viewpoints on the greenness of ILs and DESs. | Yu Chen Tiancheng Mu | 2021 | Green Chemical Engineering2021，2，2： | 11 |
| 3 | The electrochemical stability of ionic liquids and deep eutectic solvents显示文摘Room temperature ionic liquids(ILs) composed of cations and anions, as well as deep eutectic solvents(DESs) composed of hydrogen bond donors(HBDs) and hydrogen bond acceptors(HBAs), are regarded as green solvents due to their low volatility. They have been used widely for electrochemically driven reactions because they exhibit high conductivity and excellent electrochemical stability. However, no systematic investigations on the electrochemical potential windows(EPWs), which could be used to characterize the electrochemical stability, have been reported. In this regard, the EPWs of 33 ILs and 23 DESs have been studied utilizing cyclic voltammetry(CV) method and the effects of structural factors(cations and anions of ILs, and HBDs and HBAs of DESs) and external factors(electrode, water content) on the EPWs have been comprehensively investigated. The electrochemical stability of selected ILs comprising five traditional cations, namely imidazolium, pyridinium, pyrrolidinium, piperidinium and ammonium and 13 kinds of versatile anions was studied. The results show that for ILs, both cation and anion play an important role on the reductive and oxidative potential limit. For a same IL at different working electrode, for example, glassy carbon(GC), gold(Au) and platinum(Pt) electrode, the largest potential window is almost observed on the GC working electrode. The investigations on the EPWs of choline chloride(Ch Cl), choline bromide(Ch Br), choline iodide(Ch I), and methyl urea based DESs show that the DES composed of Ch Cl and methyl urea has the largest potential window. This work may aid the selection of ILs or DESs for use as a direct electrolyte or a solvent in electrochemical applications. | Qingbo Li Jingyun Jiang Guofeng Li Wancheng Zhao Xinhui Zhao Tiancheng Mu | 2016 | Science China Chemistry2016，59，5： | 6 |

| 5 | CO_(2) capture and conversion to value-added products promoted by MXene-based materials显示文摘Carbon dioxide(CO_(2) ) capture and conversion is the key route for the mitigation of the greenhouse effect and utilization of carbon sources to obtain value-added products or fuels.Much attention is paid to the development of novel materials with high CO_(2) adsorption capacity and conversion rate.MXene is the graphene-like two-dimensional metal carbide/nitride/carbonitride owning favorable structure,morphology,high surface-bulk ratio,and physicochemical properties.Here,we review the CO_(2) capture,sensing,and conversion by MXene and MXene-based materials.Furthermore,the underlying mechanism involved the capture,sensing,and conversion of CO_(2) is summarized.This review would open a new horizon for CO_(2) valorization with high efficiency and promising widespread applications. | Yu Chen Chong Liu Shien Guo Tiancheng Mu Lei Wei Yanhong Lu | 2022 | Green Energy & Environment2022，7，3： | 1 |

| 7 | Mild and efficient recovery of lithium-ion battery cathode material by deep eutectic solvents with natural and cheap components显示文摘Dissolution of lithium cobalt oxide(LCO)is the key step for the recovery of valuable metals(e.g.,Co and Li)from spent LCO-based lithium-ion batteries(LIBs).However,the dissolution process of LCO either needs toxic solvents,and high temperature,or shows low efficiency.Deep eutectic solvents(DESs)are potential green solvents to dissolve LCO.Here,DESs with polyethylene glycol(PEG)as hydrogen bond acceptor and ascorbic acid(AA)as hydrogen bond donor are found to dissolve LCO with 84.2%Co leaching efficiency at 80℃ and 72 h,which is higher than that from the reported references by common DESs.Furthermore,both DESs components(i.e.,PEG and AA)are cheap,biodegradable,and biocompatible.AA could be easily and abundantly extracted from natural fruits or vegetables.It provides a new guide for the green,mild,and efficient dissolution of LCO aiming at sustainable recovery of spent LIBs. | Yu Chen Yanlong Wang Yue Bai Minghui Feng Fengyi Zhou Yanhong Lu Yuting Guo Yixuan Zhang Tiancheng Mu | 2023 | Green Chemical Engineering2023，4，3： | 0 |
