| 摘要 |
The present invention relates to hydrogen generating microporous metals, methods for preparing microporous metals, and methods for producing hydrogen from water using the metals and systems of the invention. In particular, microporous metals selected from the group comprising aluminum (Al), magnesium (Mg), silicon (Si), Iron (Fe) and zinc (Zn), capable of producing hydrogen upon reaction of the metal with water having a neutral pH are provided. Methods for preparing microporous metals comprising the steps of selecting a metal that is sufficiently electropositive (i.e. water reactive); and introducing microporosity in the selected metal by means of mechanical deformation, or metallurgical techniques, in order to generate the microporous metal are also provided, as is a method for producing hydrogen comprising reacting a microporous metal powder with water at a pH of between 4 and 10.
