Abstract:
Titanium suboxide (TixO2x-1) nanoparticles useful as a support for a catalyst electrode of a fuel cell, and a method for synthesizing the titanium suboxide (TixO2x-1) nanoparticles by using TiO2, a Co catalyst and hydrogen gas at a low temperature ranging from 600 to 900° C. are described Since the titanium suboxide nanoparticles show high corrosion resistance to acid and durability and have excellent thermal and electric conductivities, a catalyst electrode manufactured by using the same as a support exhibits improved catalytic activity and oxidation reduction (redox) properties.
