Development of Potential Electrocatalyst: Highly Multiporous WO3-rGO Nanocomposites for Enhancing Electrocatalytic Oxygen Evolution Reactions

The development of sustainable energy technologies, such as fuel cells and metal-air batteries, necessitates the use of a highly efficient electrocatalyst for the oxygen evolution process. The fabrication of WO3-rGO nanocomposites results in the formation of a multiporous nanostructure. The catalytic activity of highly multiporous WO3-rGO nanocomposites containing multiporous nanostructures is shown to be significant. The catalyst has the potential to facilitate highly reactive anodic oxygen reactions, hence augmenting the synergistic impact of interfacial charge transfer and the porous structure of WO3-rGO nanocomposites. The findings of this work indicate that the use of WO3-rGO nanocomposites as electrocatalysts exhibits a considerable overpotential value of 350 mV, a Tafel slope of 67 mV dec(-1), good stability, roughness factor, and turnover frequency for the process of oxygen evolution in real-world scenarios.
