Abstract

With the progress of science and technology and the economy, realizing “sustainable development” has become the common development goal of many countries and regions in the world today. Carbon dioxide (CO₂) is widely used as an important carbon resource, which aggravates the problem of global warming. electrocatalytic Carbon Dioxide reduction reaction (ECO₂RR) is a key technology for converting CO₂ into useful carbon-based products (such as C₂H₄, CO, CH₃OH). Thereby increasing the economic and commercial value of clean energy worldwide. In this paper, different electrocatalysts commonly used in ECO₂RR reactions were studied. By summarizing the definition, characteristics, deficiencies, and modification strategies of different electrocatalysts, different effects of different electrocatalysts on ECO₂RR reaction were studied. This paper helps to make up for the shortage of different electrocatalysts in the literature review of ECO₂RR reaction, promote the development of ECO₂RR reaction electrocatalysts, and promote the progress of ECO₂RR reaction. Let the ECO₂RR reaction enable energy conservation and emission reduction, and provide more effective measures for the early realization of the “double carbon goal”. Due to the limited literature on electrocatalysts, the current research is not comprehensive. Future studies should summarize the characteristics of different electrocatalysts in ECO₂RR reactions more comprehensively.
