The utilization of CO 2 as a feedstock requires fundamental breakthroughs in catalyst design. The efficiencies and activities of pure metal electrodes towards the CO 2 reduction reaction are established, but the corresponding data on mixed‐metal systems are not as well developed. In this study we show that the near‐infrared driven decomposition (NIRDD) of solution‐deposited films of metal salts and subsequent electrochemical reduction offers the unique opportunity to form an array of mixed‐metal electrocatalyst coatings with excellent control of the metal stoichiometries. This synthetic method enabled us to develop an empirical structure–property correlation to help inform the development of optimized CO 2 catalyst compositions.
