Study of high temperature pyrolysis effects on the performance of co-doped metal-organic framework with nitrogen-doped reduced graphene oxide for the oxygen reduction reaction

In this study, the electrochemical performance of nitrogen-doped reduced graphene oxide (N-rGO) combined with cobalt-doped MOF catalyst is investigated after annealing at different temperatures for application with proton-exchange membrane fuel cells (PEMFCs). The material was characterized using FTIR and Raman spectroscopy, XRD, SEM, XPS, and BET analysis to understand variations in its physical and chemical properties. Our results reveal the formation of the (100) cobalt-doped ZIF-8 phase, wit
