Progress in the design of silver-based catalysts for electrocatalytic and photocatalytic CO2 reduction to CO

Silver-based catalysts have excellent catalytic performance and high cost-effectiveness in both electrocatalysis and photocatalysis fields. The preparation of CO from CO2 by electrocatalytic and photocatalytic reduction with silver-based catalyst has high commercial value and great application prospects because of its environmental protection, energy saving, simplicity and high efficiency. Compared to other articles that focus on in-depth research within a single field, this review aims to comprehensively summarize the mechanisms and the research progress of Silver-based catalysts in electrochemical CO2 reduction and photocatalytic CO2 reduction, this will facilitate readers in gaining a more comprehensive understanding of this field.
