Hydrogen production from highly corroding Mg-based materials elaborated by ball milling

It is universally known that the reaction between magnesium or magnesium hydride and water produces hydrogen. However, this reaction stops rapidly due to the formation of a passive Mg(OH)(2) layer onto the reactive material. In this paper, we present an investigation of the hydrogen production by hydrolysis of Mg-based materials elaborated by high-energy ball milling. The best performance is obtained with a Mg-10 at.% Ni composite material milled for 30 min, which leads to a conversion yield of 100% after I h of hydrolysis in neutral aqueous solution containing chloride ions.
