An overview of Cu-based heterogeneous electrocatalysts for CO2 reduction
The electrochemical (EC) reduction of CO2 is a promising approach for value-added fuels or chemicals production. Cu-based electrode has been extensively used as a ‘star’ material for CO2 reduction to hydrocarbons. This review mainly focuses on the recent progress of Cu-based heterogeneous electrocatalysts for CO2 reduction during the last five years (2013-present). Various morphologies, oxide-derived, bimetallic Cu species and their activity on EC CO2 reduction are reviewed, providing insights for the standardization of Cu-based heterogeneous system. We also present a tutorial manual to describe parameters that set the EC CO2 reduction process especially for the pretreatment of the reaction system. That will be useful guidance for newcomers into the field. Aqueous and non-aqueous electrolyte effects based on Cu electrode are discussed respectively. Finally, the overview of reaction systems of EC/PEC CO2 reduction and H2O oxidation for Cu-based heterogeneous catalysts are provided.
