Recent advances in hydrogen generation process via hydrolysis of Mg-based materials: A short review

Mg-based hydrolysis materials with high theoretical hydrogen production yield, abundant on earth, hydrolysis products environmentally friendly characteristics are regarded as promising hydrogen generation materials. Unfortunately, the quickly formed magnesium hydroxide layer hinders further contact of inside Mg with water in the hydrolysis process, leading to its sluggish hydrogen generation rate and low yield. This paper reviews the hydrogen generation measuring methods and recent progress on the modifications for hydrolysis of Mg-based systems, including adding different type additives, forming Mg-based alloys and tuning hydrolysis solutions. The hydrolysis mechanisms of these hydrolysis systems are summarized in the article. (C) 2019 Elsevier B.V. All rights reserved.
