Cuprous oxide/ carbon nanotubes (Cu2O/MWNTs) composite superfine spheres were fabricated in situ by solution method. The products were characterized via scanning electron microscope (SEM), transmission electron microscope (TEM), X-ray diffraction pattern (XRD), UV-vis absorption spectrum and differential scanning calorimetry (DSC). The results show that the MWNTs are
embedded in cuprous oxide spheres homogeneously. Compared with pure Cu2O particle, the absorption peak of composite spheres has a tendency of blue shift, and the temperature of high temperature decomposition of ammonium perchlorate (AP) is further decreased by 11.5℃ when composite spheres act as the catalyst. In addition, the main influence on morphology and the formation mechanism of composite spheres are investigated. Results suggest that the gelatin play a key role in forming spheres and polyethylene glycol have great impact on the uniformity of spheres size.
