Aluminum, in its normal passive oxidized state, does not react with water. In this work, aluminum\nactivation is carried out using liquid metal eutectics Ga-In-Sn-Zn (60:25:10:5). Subsequently, the\nreaction with water of activated aluminum to produce hydrogen has been examined. The effects of\naluminum particle size, liquid eutectics content, and reaction temperature on hydrogen production\nrates are investigated. The liquid eutectics interaction with aluminum is discussed and the\nmechanisms of liquid eutectics penetration within the Al particles have been investigated. The\nspecific surface area of the Al particles, the mass ratio of Al to eutectics content and the reaction\ntemperature were found to determine the hydrogen production rate and yield. It is observed that\nmicro-aluminum particles of ~30 �¼m size display lower reaction rates and hydrogen yields than\n~350 �¼m size particles.
