Abstract

In this study, reduced tungsten diselenide/graphene oxide nanocomposites were successfully synthesized as an efficient electrocatalyst for oxygen reduction reaction (WSe₂/RGO) via hydrothermal method due to their unique structural features, outstanding catalytic performance along with high chemical stability. Characterizations performed using XRD, SEM and EDX techniques confirmed the successful formation of WSe₂/RGO nanocomposites. The results of electrochemical experiments indicated the excellent electrocatalytic performance of this nanostructure, including high current density and charge transfer resistance comparable to platinum-based catalysts.The findings of this study suggest that WSe₂/RGO nanocomposite can be used as an economical and efficient electrocatalyst for oxygen reduction reaction in diverse applications such as fuel cells, lithium-ion batteries, supercapacitors, and other technologies related to energy storage and conversion. These properties, together with the scalability potential of the hydrothermal synthesis method, make WSe₂/RGO nanocomposite a promising alternative to expensive catalysts in industrial applications.
