Characterization of Nickel Oxide Nanoparticles for Hydrogen Adsorption with External Electric Field

Document Type


Publication Date



Nickel oxide nanoparticles were synthesized using sodium dodecyl sulfate as the surfactant and urea as the hydrolyzing agent and different calcination temperatures and time were selected for preparation. Nitrogen adsorption (BET), X-ray diffraction (XRD) and scanning electron microscope (SEM) were subsequently used to characterize the prepared samples. The effect of an external electric field on hydrogen adsorption over a prepared nickel oxide was carried out. The electric filed was introduced by a piezoelectric element, which is capable of autogenously generating charges under hydrogen pressure. Increased hydrogen adsorption was obtained from this study, which indicated a stronger interaction between the adsorbent surface and hydrogen. © 2012 The Minerals, Metals, & Materials Society.
