Ni alloy nanowires as high efficiency electrode materialsnfor alkaline electrolysers

Hydrogen production by water electrolysis (WE) is a very promising technology because it is a pollution-free process especially if renewable sources are employed to energy supply. Nowadays, the cost of hydrogen production by WE is higher than other available technologies, which makes WE not competitive. Many efforts have been made to improve WE performance, through the use of electrodes made of transition metal alloys as cathode and compound of metal oxide as anode [1]. In the field of water-alkaline electrolyzer, the development of cheap nanoporous based nickel electrodes with high electrocatalytic features is one of the potential approaches to increase the WE performance [2].
