Executive Summary : | As a primary oxidizer in solid composite propellants, ammonium perchlorate (AP) show a crucial function because its thermal decomposition behavior has a straight influence on the characteristic of solid composite propellants. To ameliorate the action of solid composite propellant, it is essential to take measures to qualify the thermal decomposition behavior of AP. In recent years, transition metal oxides and carbon-supported transition metal oxides have attracted appreciable attraction due to their exceeding catalytic activity.rGO/ABO3 type pervoskite oxide nanohybrids will be successfully adorned on the surface of the rGO sheets through a easy, one-step chemical method. rGO/ABO3 type pervoskite oxide nanohybrids will homogeneously be supported on the rGO sheets. Preliminary results show that The rGO/ABO3 type pervoskite oxide nanohybrids will exhibit amazing catalytic activity on thermal decomposition of ammonium perchlorate (AP) based propellants.The rGO/ABO3 type pervoskite oxide nanohybrids will further be characterized by XRD, FT-IR, XPs, TEM, Raman, BET,XPs techniques. The rGO/ABO3 type pervoskite oxide nanohybrids would confirm astonishing catalytic activity on thermal decomposition of ammonium perchlorate (AP), which is better than that of bare mono/bi transition metal NPs.This enhanced catalytic performance will be principally attributed to the synergistic effect of rGO/ABO3 type pervoskite oxide nanohybrids and rGO.The HTD activation energy on a conversion degree () range from 0.05 to 0.95 of propellant samples would be investigated by two model-free methods Flynne-Walle-O zawa (FWO) and Kissinger-Akahira-sunose (KAs). The results would expect that both methods may have similar values of Ea, and they match well with each other. A strong dependence of Ea on a reveals a complex decomposition process. The model-fitting analysis will suggest the HTD process of propellant samples with or without catalysts both followed First order reaction model. |
