Hydrogen Storage in Mesoporous Metal Oxides with Catalyst and External Electric Field

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.

High temperature selective sensing of hydrogen with MgO-modified SrMoO4 micro-fibers

“…The current authors (Ciftyurek et MgO was based on the fact that it is a known H 2 dissociation catalyst [17], as well as, a support in transesterification, double-bond isomerization, self-and cross-condensation reactions [18,19]. A secondary MgO phase on the SrMoO 4 would catalytically modify the SrMoO 4 surface which would potentially increase reversible [20,21,22], homolytic [23,24], and/or heterolytic [25,26] dissociative adsorption processes towards H 2 [27,20,28,29] and H 2 uptake capability [30,31,32].…”

The role of density functional theory methods in the prediction of nanostructured gas-adsorbent materials

“…1), two families of GAM which at present are being investigated also very thoroughly [70][71][72][73][74]. For the sake of focus, other important mechanisms exploited in gas storage and sequestration processes (e.g., gas binding in bulk chemical form and thermodynamic destabilization of nanocrystals and clusters [75][76][77][78][79]) and related families of materials (e.g., metal oxides and binary and ternary hydride compounds [80][81][82][83][84][85]), will not be discussed exhaustively in the present work.…”

Hydrogen Storage for Energy Application

“…It was observed that the capacity of hydrogen adsorption in metal oxide increased remarkably when Pt was introduced into mesoporous nickel oxide and magnesium oxide [29].…”
