AbstractHydrogen reaction kinetics of nanocrystalline MgH₂ co-catalyzed with Ba3(Ca₁₊xNb₂₋x)O₉₋δ (BCN) proton conductive ceramics and nanoparticle bimetallic catalyst of Ni/Pd dispersed on singlewall carbon nanotubes (SWNTs) support has been investigated. The nanoparticle bimetallic catalysts of Ni/Pd supported by SWNTs were synthesized based on a novel polyol method using NiCl₂·6H₂O, PdCl₂, NaOH and ethylene glycol (EG). The nanostructured Mg composites co-catalyzed with BCN and bimetallic supported catalysts exhibited stable hydrogen desorption capacity of 6.3–6.7 wt.% H₂ and the significant enhancement of hydrogen desorption kinetics at 230–300 °C in comparison to either non-catalyzed MgH₂ or the nanocomposite of MgH₂ catalyzed with BCN.
