CO2 electroreduction offers a promising approach to alleviate global warming and reduce petroleum consumption simulta-neously,due to its capability to convert the greenhouse gas CO2 to valuable fuels and chemicals by using renewable electricity.Electrocatalyst has an essential impact on the CO2 electroreduction performance.Among the diverse exploited materials,Cu is the only monometallic electrocatalyst that can produce CO and hydrocarbons.However,its activity,selectivity,and durability are not satisfactory for practical applications.Here,we make a comprehensive survey of the recent progress in enhancing Cu-based electrocatalysts with the strategies such as oxidation pre-treatment,heteroatom doping,morphological control,and surface modification.This review provides an overview of the current status and future opportunities for Cu-catalyzed CO2 electro-reduction.It may contribute to the rational design of Cu-based electrocatalysts with improved performance and thus advance practical CO2 electrolyzer development.

A highly enantioselective 1,3-dipolar cycloaddition of α-substituted diazoesters with exocyclic enones was achieved with chiral scandium(Ⅲ)/N,N\'-dioxide complex as the catalyst.This protocol provided a facile and efficient route to optically active 1-p
The unique properties of fluorine-containing organic compounds make fluorine substitution attractive for the development of pharmaceuticals and various specialty materials,which have inspired the evolution of diverse C-F bond activation techniques.Althoug
Privileged biaryl frameworks,BINOL and NOBIN,were efficiently constructed with sole 1-DNQs as arylation reagents under one set of reaction conditions.The judicious selection of palladium-catalytic system plays a pivotal role in the excellent selectivities
Photothermal therapy (PTT) is emerging as an effective treatment for superficial carcinoma.A key challenge to the effectiveness of PTT is to develop photosensitizers with high photothermal conversion efficiency.Aiming to address this challenge,we develop
The non-fully conjugated polymer as a new class of acceptor materials has shown some advantages over its small molecular counterpart when used in photoactive layers for all-polymer solar cells(all-PSCs),despite a low power conversion efficiency(PCE)caused
Two charge-transfer single crystals induced by donor-acceptor interactions were obtained.The presence of different solvent molecules led to 1D (linear) or 2D self-assembly modes.More interestingly,the 2D organic framework,a layer-by-layer 2D organic frame
Herein,a method for synthesizing various alkyl trifluoromethyl and alkyl bromodifluoromethyl ethers using carbono-fluoridothioates(R-OC(=S)F)as precursors has been described.Carbonofluoridothioates were obtained upon the reaction of an alcohol and S=CF2 g
Na-ion batteries(NIBs)are gradually attracting much attention as an alternative to lead-acid batteries and supplement to Li-ion batteries(LIBs)owing to the abundant Na resources and excellent cost-effectiveness.Since the most commonly used graphite as an
The methylation of alcohols is of great importance since a broad number of bioactive and pharmaceutical alcohols contain methyl groups.Here,a highly efficient β-methylation of primary and secondary alcohols with methanol has been achieved by using bis-N-h
