Abstract

Bimetallic Metal-Organic Framework (MOF) have attracted significant interest due to its high specific surface area and tunable porosity, leading to high sensitivity and catalytic activity. This work studies on the characteristics of Ni/Co-MOF synthesized through self-template using uniform Ni-Co glycerate spheres. Nickel and cobalt are active electrode materials with a similar properties and atomic radius, and have many possible coordination with ligands so that they can be found in many types of MOFs. In this work Ni-Co Glycerate, that was produced in powder form, was used as a source of metal ions, 2-methylimidazole (H-MeIM) as a ligand as well as aquabidest and ethanol as solvents. The MOF was produced using two step processes first is solvothermal for glycerate formation and second, is MOF formation at room temperature. The XRD results showed that the Ni/Co-MOF is in an amorphous phase because there is no peak was observed. The results of the Scanning Electron Microscope (SEM) analysis showed that the Ni/Co-MOF has spherical shape covered by nanosheets that are suspected to be amorphous MOF. In this preliminary study, we would like to explore the preparation, properties, and applications of amorphous MOF. Because amorphous MOF presents many opportunities as new functional materials especially in electrochemical applications.
