چکیده
Powered by electricity from renewable energies, electrochemical reduction of CO2 could not only efficiently alleviate the excess emission CO2, but also produce many kinds valuable chemical feedstocks. Among various catalysts, single atom catalysts (SACs) have attracted much attention due to their high utilization efficiency and expressive catalytic performances. Additionally, SACs serve as an ideal platform for investigation complex reaction pathways mechanisms thanks explicit active sites. In this review, possible generation products (mainly C1 SACs) were firstly summarized. Then, recent progress was discussed in aspect different central metal As most popular efficient coordination modulation strategy, introducing heteroatom then reviewed. Moreover, extension SACs, development dual briefly discussed. At last, some issues challenges regarding (CO2RR) listed, followed corresponding suggestions.

متن کاملHighly effective sites and selectivity of nitrogen-doped graphene/CNT catalysts for CO2 electrochemical reduction
Metal-free catalysts, such as graphene/carbon nanostructures, are highly cost-effective to replace expensive noble metals for CO2 reduction if fundamental issues, such as active sites and selectivity, are clearly understood. Using both density functional theory (DFT) and ab initio molecular dynamic calculations, we show that the interplay of N-doping and curvature can effectively tune the activ...
