Ti0.8M0.2O2-C composites are novel supports for Pt-based fuel cell electrocatalysts with enhanced stability and CO-tolerance. In this work the effect of type carbonaceous material (Vulcan XC-72, Black Pearls 2000 graphite oxide) as well mixed oxide/carbon ratio was explored on structure electrochemical performance related electrocatalysts. The were prepared by optimized routes tailored to speci...
