Electrochemical Synthesis of Copper Mesh‐Supported Thermo‐Catalysts

Abstract Metallic substrates, widely studied in the context of monolithic catalysts, offer inherent advantages in heterogeneous catalysis due to their exceptional thermal conductivity and mechanical properties. However, synthesizing stable monolithic catalysts with metallic substrates in a well‐controlled manner remains a significant challenge. Here, this work introduces a simple, cost‐efficient method to fabricate robust Cu mesh‐supported thermo‐catalysts using a modified cycling chronopotentiometry approach, where the Cu mesh serves as a donor of Cu ions. In this method, the Cu mesh surface generates two distinct layers of CuO and Cu₂O. In this context, CuO acts as the active phase, accounting for the high CO oxidation activity of Cu mesh catalysts with T₉₀ ≈ 120 °C. Additionally, these catalysts exhibit considerable potential in electrocatalysis, showcasing significant research and application value.
