Facile preparation of nickel hydroxide nanoplates on nickel foam for high performance hydrogen generation

Abstract

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.
