Electrodepositing ultra-thin Ni(OH)2 amorphous film on Ni2P nanosheets array: an efficient strategy toward greatly enhanced alkaline hydrogen evolution reaction

Abstract

The development of highly active noble-metal-free catalysts for alkaline hydrogen evolution reaction (HER) can greatly lower the cost of hydrogen economy and boost the utilization of clean and renewable energy. Herein, we report an interface-engineered nanostructure (Ni(OH)2–Ni2P/Ti) as a highly efficient HER catalyst. Impressively, the newly generated hybrid catalyst exhibits superior catalytic activity when compared to that of pristine Ni2P/Ti. It only requires overpotentials of 57 and 85 mV to afford current densities of 10 and 20 mA cm−2 in 1.0 M KOH, respectively, with its catalytic activity being retained for 24 h.
