چکیده
Electrochemical reduction reaction of CO2 (CO2RR) is a promising technology for alleviating the global warming caused by emission CO2. This technology, however, still in stage finding efficient catalysts. The catalysts must be able to convert other carbon-based products with high activity and selectivity valuable chemicals. In this review, previous development heteroatom-doped metal-free carbon materials (H-CMs) briefly summarized. Recent progress CO2RR promoted metal single-atom (M-SACs) then discussed emphasis on synthesis M-SACs, catalytic performance, mechanisms. temperature pyrolysis method electrodeposition are attracting attentions recently prepare M-SACs loading N-doped materials, very active system CO2RR. Theoretical calculations free energy change sites, Operando X-ray absorption near edge structure (XANES), Bader charge analysis reveal significant role oxidation state transfer between atoms absorbed CO. challenges perspectives extensive applications also review.

Promoter Effects of Alkali Metal Cations on the Electrochemical Reduction of Carbon Dioxide.
The electrochemical reduction of CO2 is known to be influenced by the identity of the alkali metal cation in the electrolyte; however, a satisfactory explanation for this phenomenon has not been developed. Here we present the results of experimental and theoretical studies aimed at elucidating the effects of electrolyte cation size on the intrinsic activity and selectivity of metal catalysts fo...
متن کاملPhotocatalytic carbon dioxide reduction with rhodium-based catalysts in solution and heterogenized within metal-organic frameworks.
The first photosensitization of a rhodium-based catalytic system for CO2 reduction is reported, with formate as the sole carbon-containing product. Formate has wide industrial applications and is seen as valuable within fuel cell technologies as well as an interesting H2 -storage compound. Heterogenization of molecular rhodium catalysts is accomplished via the synthesis, post-synthetic linker e...
