FeCoSe₂ Nanoparticles Embedded in g-C₃N₄: A Highly Active and Stable bifunctional electrocatalyst for overall water splitting.

ABSTRACT: To investigate cost affordable and robust HER and OER catalysts with significant low overpotentials, we have successfully embedded FeCoSe₂ spheres on smooth surfaces of graphitic carbon nitride that demonstrated high stability and electrocatalytic activity for H₂ production. We systematically analyzed the composition and morphology of Fe_xCo_1-xSe₂/g-C₃N₄ and attributed the remarkable electrochemical performance of the catalyst to its unique structure. Fe_0.2Co_0.8Se₂/g-C₃N₄ showed a superior HER activity, with quite low overpotential value (83 mV at -20 mA cm^-2 in 0.5 M H₂SO₄) and a current density of -3.24, -7.84, -14.80, -30.12
