This communication reports nickel hydroxide nanoplates grown on nickel foam (NF) by one-step water bath treatment of NF in nitric acid solution. The reaction temperature and duration were critical to the formation of nanoplates. Moreover, the Ni(OH)2 electrode on nickel foam (Ni(OH)2/NF) exhibited high performance and prominent stability toward the hydrogen evolution reaction (HER) in an alkaline solution. The mentioned finding will be expected to broaden the development of Ni(OH)2-based binder-free electrodes for electrochemical applications.
