Design and Preparation of Electrocatalysts by Electrodeposition for CO2 Reduction

Abstract

With the increasing emission of carbon dioxide (CO₂ ), the conversion and utilization of CO₂ have become a topic of increasing concern. Electrochemical CO₂ reduction reaction (CO₂ RR) is an attractive and sustainable approach for solving energy and environmental problems. Design of efficient catalysts is crucial for achieving highly efficient CO₂ RR. Different methods to prepare catalysts have been reported and used. Among them, electrodeposition is one of the common approaches, which has some obvious advantages, such as requiring simple equipment, environmentally benign. Especially, it can direct deposit catalysts on different substrates to prepare electrodes for CO₂ RR. In this review, we discuss recent advances in design and preparation of the catalysts by electrodeposition and their applications in CO₂ RR. Furthermore, the perspective of this promising area is also discussed.
