Cobalt-Doped FeSe 2-RGO as Highly Active and Stable Electrocatalysts for Hydrogen Evolution Reactions

Herein, we describe the preparation and testing of Co-doped FeSe2 hybridized with graphene (Fe1-xCoxSe2/RGO), a high-active yet stable electrocatalyst for hydrogen evolution reactions (HERs) in acidic solutions. First, we systematically analyze the composition and morphology of Fe1-xCoxSe2/RGO an…
