Electrochemical properties of Ni-P electrode materials modified with nickel oxide and cobalt

摘要

This study was undertaken in order to obtain the amorphous Ni-P layers,containing additional components as nickel oxide and cobalt powders.The choice of these materials was made on the base of the knowledge of the properties of these components in hydrogen evolution reaction.The purpose of this work was to determine surface morphology of Ni-P+NiO+Co composite layers and to evaluate their suitability as electrode materials for hydrogen evolution reaction in alkaline solution.In order to attain improvements in electrochemical properties of Ni-P+NiO+Co composite layers,they were modified by thermal and chemical treatment.Microscopic and electrochemical studies were used to characterise the layers.
