| Abstract Scope |
Electrochemical CO<sub>2</sub> reduction reaction (CO2RR) is a promising technology to produce carbon neutral fuels and chemicals. Cu is known for only materials for producing multi-carbon chemicals such as ethylene. The efficiency and selectivity of CO2RR products on Cu depend on various aspects of Cu-based catalysts, such as surface facets, and alloying elements. Here, I will discuss our efforts for selective production of C2+ products from Cu-based catalysts. First, I will highlight the crucial role of the size of Cu nanoparticles for tunable CO2R products. The low solubility limit of Cu in CeO<sub>2</sub> induces abrupt changes in the size of Cu from single atoms to nano-scale clusters. This morphological change induces the major CO2RR products varied from CH<sub>4</sub> to C<sub>2</sub>H<sub>4</sub>, respectively. Additionally, I will discuss the impact of alloying Cu with Ni and Zn on tailoring product selectivity. I will provide further details on these findings during the presentation. |
