Cu–Cr–Pb nanocomposites

摘要: In this study, we present the synthesis of Cu–Cr–Pb nanocomposites by a simple co-precipitation method and evaluate catalytic performance as-fabricated on thermal decomposition ammonium perchlorate (AP). The X-ray diffraction, scanning electron microscopy, transmission microscopy thermogravimetric analysis/differential calorimetric techniques were employed to characterize crystal phases, sizes properties as-obtained nanocomposites, respectively. results revealed that dropping Pb in CuCr2O4 could form nanocomposites. structure, size property as-synthesized are closely relevant Cu/Pb molar ratio starting reactants. Noticeably, when synthesized under condition Cu/Pb = 4:1, dispersion is better, distribution narrower, for AP more effective than those particles obtained other ratios, which may lead potential applications AP-based solid propellants future.
