Synthesis of Novel MOFs, Characterization and Electrochemical Application for Water Splitting

Abstract

Metal organic frameworks (MOF) is a porous material which is formed of organic ligand bonded with metal ion in an ordered network. Metal-organic frameworks, like zeolites, have porosities, but they may be made in an unlimited number of ways, with varying compositions and pore configurations. simple solvothermal synthesis was used to synthesize novel MOFs. The following techniques were used to characterize the synthesized MOFs: XRD, FT-IR, SEM, EDX, and TGA. The MOFs were put to the test for CO2 adsorption and electrochemical water splitting. Zn-MOF demonstrated an overpotential of 340 mV with a current density of 230 mA/cm2, YMOF (1) demonstrated a lowest overpotential of 280 mV with a current density of 180 mA/cm2, and Y-MOF (2) demonstrated the highest overpotential of 420 mV. The Zn-MOF showed the lowest charge transfer resistance, which was about 2.418 ohm. To confirm the stability of catalysts, the MOFs were additionally chronopotentiometrically evaluated, they showed good stability for ten hours. The gas adsorption capability of Y-MOF (2) was moderate.
