Аннотация: In this paper, we report the synthesis and characterization of Nitrogen-doped Graphene oxide with Metal-Organic Framework (MOF) material as a catalyst for Polymer Electrolyte Membrane Fuel Cell (PEMFC). Transition metal, Cobalt is doped into Zeolite Imidazole Frameworks (ZIF-8) in varying amounts (different molar ratios of metal prПоказать полностьюecursor to ZIF-8, 0.6, 0.9, and 1.2) to understand its effect on the catalytic performance. Various characterization techniques, viz., FTIR, Raman spectroscopy, XRD, SEM, and EDS were performed to analyze various physical and chemical properties. XRD results showed the formation of the (100) Cobalt-doped ZIF-8 phase with grain size around 20 nm. Cyclic Voltammetry studies showed that the addition of the transition metal plays a major role in the enhancement of electrochemical performance compared to that of non-transition metal carbon-based catalysts. The electrochemical performance is correlated with the physical properties for different metal precursor loadings (0.6, 0.9 and1.2 molar ratios).
