Abstract: A new potential energetic combustion catalyst, fullerene hydrazine nitrate, is prepared via a two-step process, in which fullerene hydrazine is prepared with fullerene and hydrazine hydrate, and then fullerene hydrazine reacts with concentrated nitric acid to form fullerene hydrazine nitrate. The chemical structures of products are characterized by FT-IR, UV-visible spectra, elemental analysis and X-ray photoelectron spectroscopy. The thermal stability of fullerene hydrazine nitrate is characterized by differential thermal analysis (DTA) and thermogravimetry analysis (TGA). The results indicate that the product shows a certain thermal stability in dynamic air atmosphere. The thermal decomposition behaviours of RDX and HMX in the absence and presence of fullerene hydrazine nitrate are investigated by using DTA method. The research results show that fullerene hydrazine nitrate can accelerate obviously the decomposition of RDX and HMX. The peak temperatures of the exothermal decomposition are reduced at the different heating rates of 2.5, 5, 10 and 20 ℃/min. The corresponding activation energy of RDX is decreased by about 17 kJ/mol, and that of HMX is reduced by more than 20 kJ/mol.
