The electrochemical reduction of CO2 (CO2ER) into the renewable and sustainable green fuels, such as low-carbon alcohols, is one of several workable strategies. CO2ER can be combined with renewable electricity to transform intermittent energy sources (such as wind, hydro, and solar) into a fuel that can be stored until it is ready to be used. The intrinsic characteristics of the employed catalyst have a significant and substantial effect on the efficiency of CO2ER and the ensuing economic viability. The paradigmatic multicarbon alcohol catalysts should increase the concentration of ∗CO in the reaction environment, stabilize the key intermediate products during the reaction, and facilitate the C–C coupling interaction. Since graphene has a large surface area and exceptional conductivity, it has been used as a support for active phases (nanoparticles or nanosheets). It is possible for graphene to enhance charge transport and accelerate CO2 conversion through its electronic and structural coupling effects. At the interface, a synergy can be produced that improves CO2ER by increasing ∗CO adsorption, intermediate binding, and stability. This article focuses on recent advancements in graphene-based catalysts that promote CO2ER to alcohols. Likewise, this paper also describes and discusses the key role graphene plays in catalyzing CO2ER into alcohols. Finally, we hope to provide future ideas for the design of graphene-based electrocatalysts.
