Abstract
In this work the electrochemical oxidation of methanol is studied on NiO based MOFs and its composites with reduced graphene oxides. NiO-MOF and its composites were prepared through hydrothermal method. The as-prepared materials were characterized by SEM, EDX, XRD, FTIR and Raman IR for their morphological and structural properties. The activity of prepared catalyst for oxidation of methanol was tested via cyclic voltammetry (CV) in an alkaline media on glassy carbon electrode. The electrochemical performance shows the effect of rGO concentration on methanol oxidation. The electro oxidation catalyzed by NiO-MOF and NiO-MOF/rGO composites exhibits a magnificent peak current density of 275.85 mA/cm2 at 0.8 V potential with a scan rate 50 mV/s making them a potential candidate for electrocatalysis.
