ABSTRACT:
The electrocatalytic
transformation of carbon dioxide into valuable chemical compounds has gained
increasing significance, particularly in the production of nitrogen-containing
species via C-N bond formation. This review is organized around the “nitrogen
source as the main thread, the product as the branch, and the mechanism as the
underlying logic”, summarizing and discussing the latest research work on the
formation of C-N bonds involving CO2 under electrochemical
conditions. Firstly, these works are classified by the N-containing substrates
(oxynitrides, dinitrogen gas, and ammonia) and productions (urea, amines,
amides, carbamates, and amino acids). Then, various types of electrocatalysts
are demonstrated in depth, including experimental and theoretical results.
Finally, the conclusion is presented as well as the future perspectives.
