Concerns about global warming and a potential energy crisis have driven the search for innovative methods to convert CO2, a prominent greenhouse gas emitted by fossil fuel combustion, back into fuels or other valuable molecules. Reducing CO2 emissions is critical in addressing the challenges of climate change. Carbon capture, utilization, and storage (CCUS) technologies are gaining traction to achieve net-zero emissions by converting CO2 into useful products. CO2 electrolysis is particularly promising, using renewable energy to turn CO2 into chemicals and fuels, offering a sustainable route to carbon neutrality. This approach has the potential to significantly reduce emissions and facilitate the transition to a greener future. A key strategy to achieve a carbon-neutral energy cycle involves powering electrochemical CO2 reduction (ECR) using renewable energy sources. However, ECR faces significant energy barriers due to the strong chemical inertness of CO2 molecules and the complex multi-electron transfer processes involved. ECR can yield various C1 products, including CO and CH4, as well as C2 products such as ethylene (C2H4), ethanol (C2H5OH), and ethane (C2H6). Ethane, in particular, stands out for its high energy density of approximately 1.43 MJ mol , making it a highly desirable product for energy storage and other applications. However, achieving high selectivity for ethane in electrochemical CO2 reduction is challenging, primarily due to the intricate control required for C-C bond formation and subsequent hydrogenation processes. The selective production of ethane is particularly difficult because it requires not only the formation of C-C bonds but also precise control over the hydrogenation steps to avoid over-reduction to methane or under-reduction, leading to less valuable products. Therefore, the development of high-performance electrocatalysts that can steer the reaction pathways towards ethane while minimising the production of undesired byproducts is crucial. Despite significant advancements, directing reaction pathways toward desirable products like ethane and reducing reaction potentials remain substantial challenges, necessitating the development of advanced electrocatalysts with improved product selectivity and catalytic activity.
