Experimental study on the effect of low melting point metal additives on hydrogen production in the aluminum–water reaction

Aluminum (Al) is a promising hydrogen carrier. Continuous reaction of pure Al and water (H2O) cannot proceed smoothly because Al particles are covered with a protective oxide layer. Thus, 20% Mg, Li, Zn, Bi, and Sn content were added as additives to Al–H2O reaction at high temperature. Thermogravimetric experiments were conducted to determine the reactivity of pure Al and five other samples with additives in a vapor atmosphere. Experiments...
