摘要: Chromium copper (CrCu) catalysts are well-known burning rate for solid propellants, which were used as energy source rocket propulsion [1]. The present work reports the enhancement of lithium perchlorate (LiClO4) by employing chromium a catalyst. LiClO4 decomposition depends on catalyst characteristics, such chemical composition, specific surface, and crystalline structure. Scanning electron microscopy, Brunauer-Emmett-Teller, X-ray diffraction, photoelectron spectroscopy, H2-temperature-programmed reduction analyses to characterize CrxCu(1−x)O(1+0.5x) catalysts. samples prepared using sol-gel method with different mole ratios. Furthermore, tested evaluate their effect at various temperatures. blank tests comparison shows that strongly enhance decomposition. Moreover, CuCr2O4 is formed in CrCu binary composite show smaller crystallites, larger surface area, better catalytic performance than pure CuO because interaction Cr Cu ions. This study proposes hypothetical reaction mechanism
