Abstract:

Porous Cu2O micro-spheres were synthesized without additives, using a homogeneous reactor. The effects of synthesis time and reactor rolling speed on the Cu2O micro-spheres structure were investigated. Increasing the use of polyvinylpyrrolidone, the porous Cu2O micro-spheres transformed into cubic twined crystals, and then into cubic-octahedral twined crystals. Cu2O micro-crystals with different structures were used to catalyze the thermal decomposition of ammonium perchlorate (AP). The catalytic activity of porous Cu2O micro-spheres was better than those of the cubic twined and cubic-octahedral twined crystals. The low temperature of AP decomposition decreased for 37.4 ℃ when catalyzed by the porous Cu2O micro-spheres, and amount of AP decomposed at low temperature increased from 8.7% to 49.0%.
