Abstract: The C60 arginine was prepared with C60 and arginine as the raw material. The C60 arginine lead salt was synthesized by the reaction of C60 arginine with lead nitrate, and characterized by FT-IR, MS, UV-Vis, AAS, XRD, XPS and Elemental analysis as a new combustion catalyst. The thermal stability of C60 arginine lead salt was also carried out by DSC and TG-DTG under air atmosphere, and two discrete regions of thermal decomposition can be observed in the DSC curve at 285℃ and 435℃ respectively. C60 arginine lead salt has two-steps weight loss, overall weight-loss was 57.68% in the TG-DTG curve, which shows good thermal stability.
