Catalytic thermal decomposition of ammonium perchlorate using manganese oxide octahedral molecular sieve (OMS)
The catalytic activity of mixed valent manganese oxide octahedral molecular sieve (OMS) on the thermal decomposition of ammonium perchlorate (AP) has been briefly studied. Results show that OMS plays a catalytic role on the thermal decomposition of AP, and the most effective is OMS-2. The decomposition temperature of AP has been decreased 145 °C and the heat of decomposition has been increased 0.66 kJ/g with the addition of 2 wt% OMS-2. Such effects are mainly attributed to the mixed valence of Mn3+ and Mn4+ existing in OMS-2 material and its high surface area.
