Abstract

Embodiments of the present disclosure pertain to electrocatalysts that include a surface and a plurality of catalytically active sites associated with the surface. The catalytically active sites include individually dispersed metallic atoms that are associated with heteroatoms. In some embodiments, the surface includes graphene oxide, the heteroatoms include nitrogen, and the metallic atoms include cobalt. Additional embodiments of the present disclosure pertain to methods of mediating an electrocatalytic reaction by exposing a precursor material to an electrocatalyst of the present disclosure. In some embodiments, the electrocatalytic reaction is a hydrogen evolution reaction that results in the formation of molecular hydrogen from the precursor material. Further embodiments of the present disclosure pertain to methods of making the electrocatalysts of the present disclosure by associating a surface with heteroatoms and metallic atoms.
