Abstract
Abstract With the increasing emission of carbon dioxide (CO 2 ), the conversion and utilization of CO 2 have become a topic of increasing concern. Electrochemical CO 2 reduction reaction (CO 2 RR) is an attractive and sustainable approach for solving energy and environmental problems. Design of efficient catalysts is crucial for achieving highly efficient CO 2 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 CO 2 RR. In this review, we discuss recent advances in design and preparation of the catalysts by electrodeposition and their applications in CO 2 RR. Furthermore, the perspective of this promising area is also discussed.
