Abstract

Aspects of the present disclosure generally relate to catalyst compositions including metal chalcogenides, processes for producing such catalyst compositions, processes for enhancing catalytic active sites in such catalyst compositions, and uses of such catalyst compositions in, e.g., processes for producing conversion products. In an aspect, a process for forming a catalyst composition is provided. The process includes introducing an electrolyte material and an amphiphile material to a metal chalcogenide to form the catalyst composition. In another aspect, a catalyst composition is provided. The catalyst composition includes a metal chalcogenide, an electrolyte material, and an amphiphile material. Devices for hydrogen evolution reaction are also provided.
