CoP/EEBP/N-FLGS Nanocomposite as an Efficient Electrocatalyst of Hydrogen Evolution Reaction in Alkaline Media

The search for new hydrogen evolution reaction (HER) electrocatalysts with lower cost and higher activity stability than noble metal catalysts is essential. In this regard cobalt phosphide considered one of the most promising nanomaterials. present work proposes a simple efficient method synthesis nanocomposite graphene–phosphorene structures decorated CoP nanoparticles 2–5 nm in size via electrochemical exfoliation black phosphorus carried out presence nitrogen-doped few-layer graphene followed by solvothermal Co2+-containing solution. obtained CoP/EEBP/N-FLGS demonstrates high electrocatalytic towards HER an alkaline medium. characterized overpotential 190 mV at current density 10 mA cm−2 as well small Tafel slope (78 dec−1). These characteristics make superior to based on phosphides. results study could be demand future design improvement electrocatalysts.
