Abstract
This paper presents combined metal oxide catalysts for the decomposition of ammonium perchlorate, combining two transition metal oxides (iron and cobalt) deposited on the surface of a carbon support. Combined catalysts are obtained by impregnation and chemical precipitation methods. Catalyst samples containing various phases of iron and cobalt oxides are obtained by varying the calcination temperature. The structural and morphological features of the synthesized catalysts are studied using different methods: X-ray diffraction, scanning electron microscopy, and Brunauer–Emmett–Teller surface area. As shown by the study performed using differential scanning calorimetry, the synthesized combination catalysts manifest high catalytic activity during the thermal decomposition of ammonium perchlorate, reducing the peak temperature of the high-temperature stage of decomposition by more than 60°C.
期刊介绍：
Combustion, Explosion, and Shock Waves a peer reviewed journal published in collaboration with the Siberian Branch of the Russian Academy of Sciences. The journal presents top-level studies in the physics and chemistry of combustion and detonation processes, structural and chemical transformation of matter in shock and detonation waves, and related phenomena. Each issue contains valuable information on initiation of detonation in condensed and gaseous phases, environmental consequences of combustion and explosion, engine and power unit combustion, production of new materials by shock and detonation waves, explosion welding, explosive compaction of powders, dynamic responses of materials and constructions, and hypervelocity impact.
