Summary: Electrocatalytic CO2 reduction reaction (CO2RR) has emerged as a focal point in sustainable energy research, offering the potential for closed carbon cycle. Among numerous catalysts designed for CO2RR, two-dimensional (2D) Cu-based catalysts stand out for their remarkable performance in efficiently converting CO2 into high-value-added C1 and C2+ chemicals. Herein, we discuss the recent progress and challenges in the realm of CO2RR utilizing 2D Cu-based catalysts. The first section introduces various synthetic strategies, emphasizing the features and advantages of different techniques and proposing solutions to existing challenges. The second part outlines the reaction mechanism underlying the production of C1 and C2+ products on Cu-based catalysts, then summarizes applications of different types 2D Cu-based catalysts in CO2RR. Additionally, we evaluate the limitations of 2D Cu-based catalysts and propose improved strategies. Through this exploration of research advances and challenges, we hope to illuminate the path toward developing excellent CO2 electrocatalysts.
