Abstract
Official abstract text for this publication.
Titanium suboxide (Ti x O 2x-1 ) nanoparticles useful as a support for a catalyst electrode of a fuel cell, and a method for synthesizing the titanium suboxide (Ti x O 2x-1 ) nanoparticles by using TiO 2 , 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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for synthesizing titanium suboxide (Ti x O 2x-1 , wherein x is an integer from 2 to 9), comprising: absorbing Co 2+ ions to nano-scale titanium dioxide under a presence of ethanol as a solvent; evaporating ethanol therefrom, to thereby obtain powder; and reacting the powder at a temperature ranging from 800° C. to 900° C. in an electric furnace under a reducing atmosphere, to thereby obtain titanium suboxide (Ti x O 2x-1 , wherein x is an integ…
