Abstract
The electrocatalytic reduction of carbon dioxide (CO2) is considered an effective strategy for mitigating the energy crisis and the greenhouse effect. Nickel is widely used in single-atom catalysts (SACs) owing to its special electronic structure. In this minireview, the basic principles of Ni SACs in the electrocatalytic reduction of CO2 to CO are first described. Subsequently, Ni SACs are divided into three categories depending on different strategies used to improve properties. The synthesis, morphology, performance and theoretical calculations of the catalysts are also described. Finally, an overview of the existing challenges and perspectives of Ni SACs for CO2 reduction is presented.
Keywords: CO2 reduction; Electrocatalysis; Nickel single-atom catalysts.
电催化还原二氧化碳(CO2)被认为是缓解能源危机和温室效应的有效策略。镍因其特殊的电子结构而被广泛应用于单原子催化剂(SAC)中。在本小视图中,首先介绍了镍单原子催化剂在电催化将 CO2 还原成 CO 的过程中的基本原理。随后,根据改善性能的不同策略,Ni SACs 被分为三类。此外,还介绍了催化剂的合成、形态、性能和理论计算。最后,概述了用于二氧化碳还原的 Ni SACs 目前面临的挑战和前景。
