Abstract

Orthorhombic structure perovskite ErCrO3 nanocrystals were prepared by glycine combustion method. The ErCrO3 nanocrystals were characterized by XRD, SEM, and BET. The catalytic activity measurements were carried out by DSC and TG-MS. The results indicate that ErCrO3 nanoparticles have an intense catalytic effect on the decomposition of AP. Adding 2% of ErCrO3 obtained product to AP decreases the decomposition temperature by 82°C and increases the heat of decomposition by 0.6 kJ g−1. Gaseous products of thermal decomposition of AP were NH3, H2O, O2, HCl, NO, HNO, N2O, NO2, and Cl2. The mechanism of catalytic action is based on the presence of superoxide ion (O 2 − ) and oxygenic ion (O−, O2−) on the surface of ErCrO3, and they can accelerate the thermal decomposition process of AP and the oxidation of NH3.
