초록

Titanium suboxides (TSO) are generally used in electrochemical devices due to excellent electronic conductivity and enhanced electrochemical stability. We synthesized TSO as a support material through catalytic reaction in the presence of Co catalysts at 800 degrees C in H-2 atmosphere. The Pt/TSO catalyst shows enhanced electrochemical activity and stability in oxygen reduction reaction in comparison with Pt/C.
