Reaction of Al powder with water for hydrogen generation under ambient condition

Hydrogen-generation by the reaction of pure Al powder with deionized water under ambient condition was investigated systematically. The results showed that both nano- and micro-sized Al powders could react with water and generate hydrogen under ambient pressure at mild temperature. The nanometer Al powder almost completely reacted with water at 20 °C, most of micrometer Al powders could react with water at a temperature of >40 °C, implying that...
