Abstract: In this paper, TONPs powder (titanium oxide nanoparticles powder) is prepared by anodization in 0.7 M HClO₄is annealed in N₂ at 450°C for 3 h to obtain the TONPs-N₂ powder as catalyst support to which Pdis loaded by photodeposition technique using PdCl₂ and isopropanol as sacrificial donor. The resulting Pd-TONPs-N₂ powder catalyst exhibits high surface area of 98m²/g. The catalyst support TONPs arrays powder are electrochemically characterized in basic solution of ethanol by cyclic voltammetry (CV), and chronoamperometry measurements. Pd-TONPs-N₂ powder electrode catalyst exhibits a remarkably high electrocatalytic activity and has high electrocatalytic stability for ethanol electrocatalytic oxidation reaction. Pd supported on the conductive support TONPs-N₂ is used as electro catalyst in fuel cells.
