摘要：The development of porous catalytic materials with high specific surface area and controllable active sites remains a key challenge in multiphase catalysis. In this study, we propose a methodology for the synthesis of inverse opal structured Cu2O, whereby the uniform size and thermal responsiveness of PS spheres are exploited. The removal of the template resulted in the formation of ordered macropores with a hierarchical structure, thereby providing a high specific surface area (70 m2/g), gas transport channels, and high accessibility of active sites. This approach addresses the limitations of conventional catalysts, such as diffusion resistance and low active site utilization. Porous Cu2O exhibits remarkable catalytic activity, evidenced by its accelerated decomposition of ammonium perchlorate (AP) in a non-homogeneous reaction environment. The results of gas products indicate that higher selectivity for N2 and N2O is attributable to the hierarchical structure, which correlates with the surface adsorption and conversion of NH3 and HClO4 by Cu2O. This work demonstrates that the optimized structure of porous Cu2O can deepen the understanding of the structure–property relationship of porous materials and provides ideas for the design of catalysts in non-homogeneous reactions.
