Initial Stage

Nickel and palladium nanoparticles were obtained by colloidal dispersion. Chemical reduction was used to obtain good quality nanoparticles showing electrocatalytic characteristics for improving the electrochemical hydrogen content in typical metal hydride at the initial stage of absorption process. The particle size and distribution of the colloidal nanoparticles were calculated by analyzing TEM images. The colloidal nanoparticles obtained were impregnated onto LaNi5-xMx type metal hydride alloy via catalytic dipping. The impregnated metal hydride alloy was characterized by SEM, AFM and EDS to obtain quasi-quantitative measurements of the position and concentration of the agglomerated colloidal nanoparticles forming nano-clusters onto de surface of the metal hydride alloy. Electrochemical characterization showed the enhancement of absorbed hydrogen content in the metal hydride due to the presence of agglomerated nanoparticles and the localized catalytic activity of Pd more than that of Ni nano-clusters.
