Question

why is nickel used in the manufacture of hydrogen gas

Answer 1

Answer:

CATALYST composed of nickel and iron has been developed that will make the production of hydrogen more energy efficient and cost effective. Hydrogen (and oxygen) can be produced by electrolysing water, provided that a catalyst is used to speed up the reaction.

Answer 2

Explanation:

On this catalyst there is a tiny nano-scale interface where the iron and nickel meet at the atomic level, which becomes an active site for splitting water. This is where hydrogen can be split from oxygen and captured as fuel, and the oxygen can be released as an environmentally-friendly waste,” said Zhao.
