Simple preparation of ZnO superstructures self-assembled by hexagonal prisms and their superb catalytic activity in the pyrolysis of ammonium perchlorate

ZIF-8 derived ZnO: a facile catalyst for ammonium perchlorate thermal decomposition

“…This intense exothermic peak is indicative of the complete breakdown of the remaining AP and intermediated products formed earlier. 47 In the presence of Z500 and Z750 a radical change is observed in the AP decomposition pattern. As already noted, these samples effectively catalyze the translation of a two-stage process into a single-stage process with a marked reduction in decomposition temperature.…”

“…The result indicates that Z500 has obvious catalytic efficiency towards AP thermal decomposition and this might be due to the presence of abundant (0001) planes on the surface of Z500, which is similar to previous reports. 32,47 The availability of more polar planes will facilitate the faster decomposition of ammonium perchlorate. A comparison of thermal decomposition studies of AP in the presence of MOFs [48][49][50][51] and MOF-derived metal oxides 17,18,24 is given in Table 3.…”

Combination of 3-Aminofurazan-4-carboxylic Acid and Transition Metals to Prepare Functional Energetic Catalysts for Catalyzing the Decomposition of Ammonium Perchlorate

“…Composite solid propellant (CSP), a heterogeneous energetic composite material, has an important impact on the development of the defense and space industry as a power source for missiles, aircraft, and spacecraft. − The composition of CSP includes a solid oxidizer, a polymer binder, a metal fuel, and other functional components, with the solid oxidizer occupying most of the composition (40–90 wt %). , Ammonium perchlorate (AP) is the most widely used solid oxidant and is characterized by high oxygen content, high gas release, low sensitivity to external impact, compatibility with other components, and low cost. − However, the major challenge faced by the extensive application of AP is overcoming the too-high of a decomposition temperature, accompanied by unfocused heat release, low combustion rates, and wasted raw materials. − …”

Design and preparation of core–shell AP@HNS composites with high safety and excellent thermal decomposition performance

“…3,4 In recent decades, the thermal decomposition performance of AP has been improved mainly by adding transition metals or their oxides as catalysts, such as porous b-MnO 2 , 5 nano-Co 3 O 4 , 6 and nano-ZnO. 7,8 Generally, high decomposition temperature and heat release are two crucial criteria for evaluating the thermal decomposition performance of an AP compound. However, modern composite propellants need to have higher performance with the enhancement of aerospace requirements.…”
