Abstract
A method of producing Hydrogen by reacting a metal selected from the group consisting of Aluminum (Al), Magnesium (Mg), Silicon (Si) and Zinc (Zn) with water in the presence of an effective amount of a catalyst at a pH of between 4 and 10 to produce Hydrogen. The catalyst or other additive is selected to prevent or slow down deposition of the reaction products on the (impair reactions with the) metal that tend to passivate the metal and thereby facilitates the production of said Hydrogen.

A method of producing Hydrogen comprising reacting metal particles selected from the group consisting of Aluminum (Al), Magnesium (Mg), Silicon (Si) and Zinc (Zn) with water in the presence of an effective amount of a catalyst at a pH of between 4 and 10 to produce reaction products which include Hydrogen, said catalyst is selected to be suitable for said metal particles being reacted and from the group consisting of alumina, suitable ceramic compounds containing aluminum ions, Carbon (C), calcium carbonate (CaCO3), calcium hydroxide (Ca(OH)2), polyethylene glycol (PEG), and combinations thereof, magnesium oxide (MgO), Silicon dioxide (SiO2), and Zinc oxide (ZnO) that facilitate said reacting said metal with said water and improves production of said Hydrogen.
