Abstract:
Design and exploration of highly efficient oxygen evolution reaction (OER) electrocatalysts is an urgent task to realize the future ideals of the hydrogen economy. Non-precious metal-based nanomaterials have been widely developed as electrocatalysts to expedite reaction rate and solve the low efficiency problem of the OER. A novel nanocatalyst, NiSe-CoFe LDH, in which lamellar CoFe LDH covered the surface of NiSe, was fabricated through a simple chemical vapor deposition and hydrothermal method. The specific heterogeneous three-dimensional structure of NiSe-CoFe LDH showed impressive electrochemical performance towards the OER. When used as an OER electrocatalyst, the NiSe-CoFe LDH nanomaterial afforded an overpotential of 228 mV to attain 10 mA cm-2. Furthermore, NiSe-CoFe LDH also maintained excellent stability with negligible activity after chronopotentiometry measurement for 60 hours.
