Abstract

The search for effective electrocatalysts for energy conversion is crucial for the advancement of green energy. Electrodeposition is a simple but effective method of preparing improved electrodes for use in the electrochemical sector. In the present work, we have synthesized amorphous NiMoSe nanospheres on Ni foam (NF) via a simple electrodeposition method. The synthesized NiMoSe demonstrates outstanding catalytic activity for the hydrogen evolution reaction (HER), with a small overpotential of 130 mV at a current density of 10 mA cm−2 in 1 M KOH electrolyte and a small Tafel slope of 59 mV dec−1. Furthermore, NiMoSe also shows long-term durability over 45 h.
