    • 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.
    • 本公开的实施方案涉及包括与表面相关联的表面和多个催化活性位点的电催化剂。 催化活性位点包括与杂原子相关的单独分散的金属原子。 在一些实施方案中,表面包括氧化石墨烯,杂原子包括氮,并且金属原子包括钴。 本公开的另外的实施方案涉及通过将前体材料暴露于本公开的电催化剂来介导电催化反应的方法。 在一些实施方案中,电催化反应是析氢反应,其导致从前体材料形成分子氢。 本公开的另外的实施方案涉及通过将表面与杂原子和金属原子缔合来制备本发明的电催化剂的方法。
