Doping nikel (Ni) metal in zeolitic imidazolate framework-8 using green synthesis method

Abstract

Ni-Doping Ni metal into ZIF-8 material aims to increase the ability of ZIF-8. Ni-ZIF-8 was synthesized using an environmentally friendly method by reusing methanol as a solvent in the previous process and carried out at room temperature. The ratio of the molar ratios used was 1:4:4 for Zinc nitrate:2methylimidazolate: TEA. As an effort to save the environment from the dangers of waste caused by the filtrate, Ni-ZIF-8 was then synthesized using the same filtrate up to six times. Based on the results of characterization using XRD, FTIR and SEM showed that the Ni-ZIF-8 material synthesized using the filtrate had similarities with Ni-ZIF-8 synthesized with pure methanol.
