摘要
In this paper, an effective method for synthesizing three different catalysts Mo-MOF, MO/NPC, and MO-MS/NPC by solvothermal preparation and pyrolysis processes has been described. The structural and compositional characteristics of these catalysts have been thoroughly analyzed using SEM, XRD, XPS, FTIR, and TEM characterization techniques. It is noteworthy that MO-MS/NPC has proven to have remarkable electrocatalytic capabilities, exhibiting high current density i.e., 354.3 mA/cm2 and stability in methanol oxidation as well as superior electrocatalytic activity for oxygen reduction reactions Because of these qualities, MO-MS/NPC, MO/NPC, and Mo-MOF might be an attractive option as cathodic and anodic materials in direct methanol fuel cells (DMFCs). Their higher oxygen reduction abilities as cathode materials can boost the cathodic reaction's effectiveness and encourage the conversion of oxygen and protons into water, and also help methanol to oxidize into carbon dioxide at the anode, liberating electrons that can be used to produce electricity.
