Advances in Hydrolysis of Magnesium and Alloys: A Conceptual Review on Parameters Optimization for Sustainable Hydrogen Production

Metals, Год журнала: 2025, Номер 15(4), С. 363 - 363

Опубликована: Март 26, 2025

This review explores hydrogen production via magnesium hydrolysis, emphasizing its role in the energy transition. Articles were selected from Scopus database based on novelty. Magnesium’s abundance, high reactivity, and potential for recycling industrial waste make it a strong candidate sustainable production. A key advantage is use of non-potable water, enhancing environmental economic benefits. major challenge passivating Mg(OH)2 layer, which limits release. Recent advances mitigate this issue through additives (metals, oxides, salts), alloying (Ni, La, Ca), mechanical treatments (ball milling, cold rolling), diverse reaction media (seawater, acids, saline solutions). These strategies significantly improve yields kinetics, enabling scalability. Magnesium hydrolysis exhibits wide activation range (3.5–102.6 kJ/mol), highlighting need optimization additives, concentration, temperature, medium composition. Critical factors include additive selection, particle size control, alloying, while secondary have minimal impact. underscores as promising, circular, economy-compatible method generation. Despite challenges balancing efficiency impact, recent advancements provide solid foundation scalable,
