Ni/ZIF-8 catalyst has been synthesized and characterized; the supporting materials, zeolitic imidazolate framework-8 (ZIF-8), were prepared by room temperature-synthesis method with slight modification using methanol as a solvent and then deposited with monometallic nickel via wetness impregnation technique. Furthermore, the synthesized ZIF-8 and Ni/ZIF-8 were characterized by FTIR, BET, XRD, and SEM-EDS techniques. The results obtained that the physicochemical properties, i.e., specific surface area, pore volume, and pore size, of Ni/ZIF-8 were lower than those of the ZIF-8 sample observed by BET analysis. Based on the structure analysis, the FTIR spectra and the XRD pattern of Ni/ZIF-8 were almost identical trends to that of pure ZIF-8. The surface morphology of Ni/ZIF-8 catalyst observed by SEM analysis depicted the occurrence of the agglomeration between the particles that make up the Ni/ZIF-8. The presence of Ni particles in the Ni/ZIF-8 was confirmed by SEM-EDS analysis. In summary, the loading of the Ni ions has no significant effect on the structural and morphological of ZIF-8, and vice versa has an impact on their psychochemical properties. Furthermore, it can be a guide for researchers on the use of Ni/ZIF in catalytic activity tests for suitable various reactions. [ABSTRACT FROM AUTHOR] |
