Abstract

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.

期刊介绍： Catalysis Letters aim is the rapid publication of outstanding and high-impact original research articles in catalysis. The scope of the journal covers a broad range of topics in all fields of both applied and theoretical catalysis, including heterogeneous, homogeneous and biocatalysis. The high-quality original research articles published in Catalysis Letters are subject to rigorous peer review. Accepted papers are published online first and subsequently in print issues. All contributions must include a graphical abstract. Manuscripts should be written in English and the responsibility lies with the authors to ensure that they are grammatically and linguistically correct. Authors for whom English is not the working language are encouraged to consider using a professional language-editing service before submitting their manuscripts.
