Effect of nano-metal oxide and nano-metal oxide/graphene composites on thermal decomposition of potassium perchlorate

In this paper, the CoO/graphene, CuO/graphene, and Fe2O3/graphene composite particles were successfully prepared by liquid deposition method. The crystal structure, morphology and specific surface area of the composite particles were analyzed by XRD, SEM and BET. Micromorphology analysis showed that CoO, CuO, and Fe2O3 were uniformly loaded on graphene slices. The catalytic effect of each catalyst on the thermal decomposition of potassium perchlorate (KP) was investigated by DSC. The results show that CoO/graphene has the best catalytic performance.
