In recent times, electrocatalytic carbon dioxide discount (CO2RR) expertise, which is powered by renewable vitality and may exactly management the response path underneath gentle circumstances, has attracted in depth consideration from each the tutorial and industrial communities. Two-dimensional materials catalysts have grow to be a key technique for selling CO2RR attributable to their structural benefits. Nonetheless, the regulatory mechanism by which the quantity and measurement of lively heart atoms have an effect on the efficiency of CO2RR stays unclear, which hinders the rational design of catalysts. On this overview, the most recent progress of two-dimensional materials catalysts corresponding to single-atom, diatomic, triatomic and metallic cluster based mostly on CO2RR. Firstly, the fundamental means of CO2RR was summarized, revealing the structure-activity relationship between the variety of lively 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 in addition critiques the related contents of density practical idea (DFT) calculation and electrocatalysis, offering a foundation for the optimization and mechanism analysis of CO2RR catalysts.
