Lately, electrocatalytic carbon dioxide discount (CO2RR) expertise, which is powered by renewable power and may exactly management the response path beneath gentle situations, has attracted intensive consideration from each the educational and industrial communities. Two-dimensional materials catalysts have turn out to be a key technique for selling CO2RR as a result of their structural benefits. Nevertheless, the regulatory mechanism by which the quantity and dimension of energetic heart atoms have an effect on the efficiency of CO2RR stays unclear, which hinders the rational design of catalysts. On this evaluation, the newest progress of two-dimensional materials catalysts corresponding to single-atom, diatomic, triatomic and steel cluster primarily based on CO2RR. Firstly, the fundamental technique of CO2RR was summarized, revealing the structure-activity relationship between the variety of energetic facilities and the properties of two-dimensional supplies. As well as, this paper not solely expounds the benefits and drawbacks of various catalysts, elaborates on the mechanism of CO2 discount to C1 intimately, but additionally critiques the related contents of density purposeful concept (DFT) calculation and electrocatalysis, offering a foundation for the optimization and mechanism analysis of CO2RR catalysts.
