摘要

电化学二氧化碳还原反应(CO2RR)是减轻环境污染和实现碳循环的一种途径,它能将二氧化碳转化为高附加值的化学品和燃料。近来,催化剂的脱ocalization 状态调节已成为评估 CO2RR 催化性能的一种有效方法。研究发现,催化剂的脱ocalization 状态可促进 CO2RR 的稳定性和选择性,其基本原理是增强催化剂的电子传导性或调节中间产物的吸附性。在这篇微型综述中,我们首先讨论催化剂的脱ocalization 状态如何影响其催化特性。然后,我们分两部分总结了这一主题的最新进展:CO2RR 的稳定性和选择性。我们特别强调了选择性部分,将其分为两个部分:氢吸附和 CO2RR 中间产物。最后,我们通过概述该领域所面临的挑战和对未来研究方向的看法,以一些意见结束本综述。

Effects of the delocalization state on electrocatalytic CO2 reduction: a mini-review

The electrochemical carbon dioxide reduction reaction (CO2RR) is a way to alleviate environmental pollution and realize carbon recycling, which converts CO2 into value-added chemicals and fuels. Recently, the delocalization state regulation of catalysts has emerged as an effective method to evaluate the catalytic performance in CO2RR. The delocalization state of catalysts has been found to promote the stability and selectivity of CO2RR, which is essentially based on enhancing the electron conductivity of catalysts or regulating the adsorption of intermediates. In this mini-review, we first discuss how the delocalization state of catalysts affects their catalytic properties. Then, we summarize recent progress on the subject in two parts: stability and selectivity of CO2RR. In particular, we have emphasized the selectivity part, breaking it into two components: hydrogen adsorption and CO2RR intermediates. Finally, we conclude the review with some observations by outlining the challenges and presenting our viewpoints on the future research directions in this field.
