Metal-organic frameworks are one of the materials that currently have the potential as an anode material to replace graphite. It also has the advantages of large specific surface area, storage space and high gas absorption with high pore volume and good conductivity. The purpose of this study was to determine the optimum temperature for the synthesis of Metal-Organic Frameworks to obtain conductivity performance. Zinc nitrate hexahydrate and acetic acid were mixed in N, N-Dimthylformamide solvent at various temperatures of 250-650 ℃ for 4 hours with a slow pyrolysis process and proceeded with precipitation. Solid Metal-Organic Frameworks formed were characterized using Scanning Electron Microscopy, X-ray diffraction, Fourier Transform Infra-Red, and IV-Meter. The crystal form is nanocubes of a layered metal-organic framework of Zinc (II) that penetrates each other in a hexagonal shape. The crystal contains zinc oxide with hydroxyl and carboxylic functional groups. Metal-organic synthesis occurs at an optimum reaction temperature of 450 ℃, showing high conductivity, with the fastest current increase, reaching a current of 3.82E-08 A at a voltage of 0.05 V. © 2024 EDP Sciences.
