摘要

Metal-doped ZIF-67 (M-Z, M = Ni, Cu) was prepared by liquid phase precipitation method, and its microstructure, crystal structure, and specific surface area were determined by characterization methods such as SEM, TEM, FTIR, XRD, XPS, BET, etc. SEM and TEM images show that M-Z is a regular dodecahedron, maintaining the basic morphology of ZIF-67. FTIR and XRD confirm the existence of the crystal structure, and XPS reveals the elemental composition of M-Z, proving the successful doping of the metal. BET data shows that M-Z has an excellent specific surface area, providing favorable conditions for catalysis. The thermal decomposition kinetics and thermodynamics of M-Z on the catalytic decomposition of nitrocellulose at different heating rates (5, 10, 15, 20 K·min− 1) were studied using DSC. According to the findings, Ni-Z exhibited the greatest catalytic activity on nitrocellulose, with the decomposition temperature advanced by 3.4 ℃ and the activation energy reduced by 12.93 kJ·mol− 1.
