	                	Cu2O micro-spheres were fabricated by a solvothermal method using poly vinylpyrrolidone (PVP) as an additive. The influences of PVP dosage and reaction temperature on the morphologies of the products were investigated. Cu2O micro-spheres with diameters of 100-200 nm and about 1 μm were synthesized with reaction time of 2.5 and 4.5 h, respectively. Meanwhile, differential thermal analysis (DTA) was used to determine the catalytic performance of these Cu2O micro-spheres with different diameters for thermal decomposition of ammonium perchlorate (AP). Adding 2% (w) Cu2O micro-spheres with diameters of 100-200 nm and about 1 μm into AP decreased the maximum temperature of AP decomposition by 116 and 118 °C, respectively, and increased the amount of AP decomposed at lower temperature.
