With a colloid method, RuO2 was deposited on Sb-doped SnO2 nanoparticles (ATO, Aldrich, 30-40 nm), which was employed as a novel support material for anode catalysts of polymer electrolyte membrane water electrolysers (PEMWE). Distinctive RuO2 nanoparticles (10-15 nm) were stably deposited on ATO nanoparticles, which were characterized with XRD and SEM. RuO2/ATO exhibited higher activity than unsupported RuO2 for oxygen evolution. A PEMWE single cell with 10 mg cm(-2) 20 wt.% RuO2/ATO achieved 1.56 V at 1 A cm(-2) at 80 degrees C.
