g-C3N4/NiO composites were prepared by a simple mixing-calcination method. The structure and morphology of g-C3N4/NiO were characterized by X-ray Diffraction (XRD), Fourier Transform Infrared Spectrometer (FT-IR), Field Emission Scanning Electron Microscopy (FESEM) and Energy Dispersive X-ray spectroscopy (EDS). The catalytic effect of g-C3N4/NiO on thermal decomposition of ammonium perchlorate (AP) was investigated by Differential Thermal Analysis (DTA) and Thermo Gravimetric Analysis (TG). The results show that nanometer NiO is uniformly dispersed on the surface of g-C3N4, g-C3N4/NiO composites make the two decomposition peaks of AP combine and the high-temperature decomposition peak value of AP decrease by 62.5℃, which exhibits good catalytic performance. The catalytic activity of g-C3N4/NiO is much higher than that of single-phase g-C3N4 and NiO, clearly demonstrating a synergistic effect between g-C3N4 and NiO.
