Thermal decomposition of ammonium perchlorate catalyzed with CuO nanoparticles

摘要: Abstract Ammonium perchlorate (APC) is the most common oxidizer in use for solid rocket propulsion systems. However its initial thermal decomposition an endothermic process that requires 102.5 J·g−1. This manner involves high activation energy and could render burning rate regime. study reports on sustainable fabrication of CuO nanoparticles as a novel catalyzing agent APC oxidizer. Colloidal with consistent product quality were fabricated by using hydrothermal processing. TEM micrographs demonstrated mono-dispersed particles 15 nm particle size. XRD diffractogram highly crystalline material. The synthesized colloidal effectively coated via co-precipitation fast-crash solvent–antisolvent technique. impact copper oxide behavior has been investigated DSC TGA techniques. stage at 242 °C subsequent two exothermic stages 297.8 °C 452.8 °C respectively. At 1 wt%, offered decrease 30%. main outcome this peaks merged into one single peak increase total heat release 53%. These features can inherit unique ability advanced energetic
