Abstract

The effects of catalyst and external electric field on hydrogen storage were evaluated for mesoporous nickel oxide and magnesium oxide. When Pt was introduced into the metal oxides, the capacity of hydrogen adsorption increased remarkably. Furthermore, the measurements of hydrogen adsorption were also carried out on metal oxides by using piezoelectric materials PMN-PT to generate the external electric field. It was observed that the external electric field can increase hydrogen uptake by 37.5% for nickel oxide and 25% for magnesium oxide in a pressure range from 0 to 60 bar. Our DFT calculations support this electrical field enhancement. © 2010 American Chemical Society.
