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.

铜网负载热催化剂的电化学合成

金属基材在整体催化剂的背景下得到了广泛研究，由于其优异的导热性和机械性能，在多相催化中具有固有的优势。然而，以良好控制的方式合成具有金属基底的稳定整体催化剂仍然是一个重大挑战。在这里，这项工作介绍了一种简单、经济高效的方法，使用改进的循环计时电位法来制造坚固的铜网支撑热催化剂，其中铜网充当铜离子的供体。在此方法中，铜网表面生成两个不同的 CuO 和 Cu ₂ O 层。在这种情况下，CuO 充当活性相，说明铜网催化剂在 T ₉₀ ≈ 120 °C 时具有高 CO 氧化活性。此外，这些催化剂在电催化方面表现出巨大的潜力，具有重要的研究和应用价值。
