The development of inexpensive and effective electrocatalyses are all-important for hydrogen production from water electrolysis. In this study, a facile design of a reduced graphene oxide (rGO) based electrocatalyst decorated with nickel nanoparticles is described. The voltammetric results and the hydrogen evolution reaction (HER) kinetics showed that the as-prepared nanocomposite is an effective and stable electrocatalyst for hydrogen production with a small Tafel slope of 152 mVdec-1 and long-term continuous durability (over 24 h) in 0.5 M H2SO4 solution. Also, the enhanced HER activity was confirmed by characterization results with the porous/greater electroactive surface area. The remarkable increase in electrocatalytic activity was due to the surface roughness and the synergetic chemical coupling effects between rGO and Ni nanoparticles.
