Abstract

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.
