Ingenious design of catalysts structure is vital for accelerating ammonium perchlorate (AP) thermal decomposition at lower temperature and accompanying with more heat release. In this work, a self-templated approach is adopted to construct hierarchical hollow double-shelled Co3O4 using cobalt glycerate solid spheres as precursors. The structural transformation from the solid species to the hollow double-shelled Co3O4 sphere is implemented by a solution growth combined with a subsequent calcination. The hierarchical hollow double-shelled morphology, large surface area and unique electronic structure endue Co3O4 with enhanced catalytic performance for thermal decomposition of AP. The AP decomposition temperature is decreased to 318 °C and heat release is increased from 491 J g−1 to 1280 J g−1.

高氯酸铵强化热分解分层空心双壳Co3O4的构建

催化剂结构的巧妙设计对于在较低温度下加速高氯酸铵 (AP) 热分解并伴随更多热量释放至关重要。在这项工作中,采用自模板方法,以甘油酸钴固体球体为前驱体,构建了分层中空双壳 Co 3 O 4。从固体物质到空心双壳 Co 3 O 4球的结构转变是通过溶液生长结合随后的煅烧来实现的。Co 3 O 4 具有分层中空双壳形貌、大表面积和独特的电子结构具有增强的 AP 热分解催化性能。AP分解温度降低到318℃,放热从491 J g -1增加到1280 J g -1
