We first propose the theoretical design principles for 2D electrodes, including stability, electronic properties, capacity, and ion diffusion descriptors. Next, classified examples of promising 2D electrodes designed by theoretical simulations are given, covering graphene, phosphorene, MXene, transition metal sulfides, and so on.

However, the requirement of high-overpotential for obtaining reasonable current, low Faradaic efficiencies (FE) and low intrinsic catalytic activities require the optimisation of the CuSn nanoarchitecture for the further advancement in the field. In the current work, we have optimised Sn loading on Cu gas diffusion electrodes (GDEs) by electrochemical spontaneous precipitation. Samples with various Sn loadings were tested in a three-chamber GDE reactor to evaluate their CO2 reduction performances. The best performance of 92% CO Faradaic efficiency at a cathodic current density of 120 mA cm−2 was obtained from the 20 min Sn deposited Cu2O sample operated at −1.13 V vs. RHE. The electrocatalyst had ∼13% surface coverage of Sn on Cu GDE surface, and had Sn in oxide form and copper in metallic form. The catalyst also showed stable performance and was operable for >3 h under chronoamperometric conditions. The surface of the GDE reduces from Cu2O to Cu during eCO2R and goes further reconstruction during the eCO2R.

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.
