Abstract: Ru0.1Ti0.9O2 nanopowder was synthesized from TiN nanoparticle and RuCl3 precursors by the impregnation-thermal decomposition method. The supported Pt/Ru0.1Ti0.9O2 electrocatalyst was then prepared by solid phase synthesis. Pt/Ru0.1Ti0.9O2 showed much better stability than Pt/C in an anti-polarization experiment. Pt/Ru0.1Ti0.9O2 also showed much better electrocatalytic properties as a PEMFC cathodic catalyst by modifying a membrane electrode.

Key words: titanium nitride, ruthenium oxide, titania, impregnation-thermal decomposition, fuel cell, water electrolysis, catalyst support, conductive oxide
