Novel bulk catalysts based on CoMn mixed oxides were prepared by a coprecipitation method for rocket-grade hydrogen peroxide decomposition. A 2 N thruster was used to evaluate and compare the catalysts in continuous and pulsed firings. The aluminum-containing mixed oxide catalyst, CoMnAl, provided the best performance, spontaneously decomposing the propellant and sustaining several thermal cycles without fractures and deactivation. Because experimental results were close to theoretical ones, this material has a good potential for peroxide decomposition in satellite and auxiliary propulsion systems.
