Abstract

Al water reaction is one of the preferred hydrogen production methods. However, the passive oxide film which forms on the surface of Al particles that prevents or delays the reaction during this reaction is a problem. In this study, in order to overcome this problem ball milling was applied and NaOH solutions with different concentrations were used in the reactions. Al powders were ball milled with NaCl and 0.5, 1, 1.5, 2 M NaOH solutions were used in the experiments. Effect of alkaline concentration was investigated on the hydrogen generation experiments. The results showed that, higher temperatures and increased concentrations of NaOH solutions improves the hydrogen generation rate.
