Abstract

The electrochemical CO₂ reduction reaction (CO₂RR) offers a green and sustainable process to convert CO₂ into valuable chemical stocks and fuels. Metal is one of the most promising types of catalysts to drive an efficient and selective CO₂RR. The catalytic performance of metal nanocatalysts is strongly dependent on their structural features. Recently, phase engineering of nanomaterials (PEN) has emerged as a prominent tactic to regulate the catalytic performance of metal nanocatalysts for the CO₂RR. A broad range of metal nanocatalysts with conventional and unconventional crystal phases has been developed, and remarkable achievements have been made. This review summarizes the most recent developments in phase engineering of metal nanocatalysts for the electrochemical CO₂RR. We first introduce the different crystal phases of metal nanocatalysts used in the CO₂RR and then discuss various synthetic strategies for unconventional phases of metal nanocatalysts. After that, detailed discussions of metal nanocatalysts with conventional and unconventional phases, including amorphous phases, are presented. Finally, the challenges and perspectives in this emerging area are discussed. © 2022 The Authors
