Crystalline/amorphous nickel sulfide interface for high current density in alkaline HER: surface and volume confinement matters!
Prince J. J. Sagayaraj, Karthikeyan Sekar
Abstract
In this report, we have developed a novel CA interface between crystalline and amorphous nickel sulfide which required a low overpotential of 15 mV for 10 mA cm −2 with the intrinsic activation for alkaline hydrogen evolution reaction.
