The catalytic activity of transition metal oxide nanoparticles on thermal decomposition of ammonium perchlorate
Abstract
The catalytic proficiency of three MONs for AP thermal decomposition was studied in this work. A chemical co-precipitation method was used for synthesis of MONs (CuZnO, CoZnO, and NiZnO) and their characterization carried out by utilizing XRD, FTIR, and SEM. The TGA/DSC technique was employed for the investigation of the catalytic proficiency of MONs on the AP. The DSC data were used for measuring activation energy of catalyzed AP by using Ozawa, Kissinger, and Starink method. The MONs were much sensitive for AP decomposition, and the performance of AP decomposition was further improved. Among all the MONs, the CuZnO exhibits higher catalytic action than others and decomposition temperature of AP is descending around 117 °C by CuZnO. The reduction in the activation energy was noticed after the incorporation of MONs in AP. Keywords: Metal oxide nanoparticles (MONs), Ammonium perchlorate (AP), Catalytic activity, Activation energy
