Paper Title:
A New Composite Electrocatalyst, TiO2/AC, for Oxygen Reduction in Zinc-Air Battery
  Abstract

A new composite electrocatalyst, well-dispersed TiO2/active carbon (AC), has been assessed with regard to its applicability for oxygen reduction in air electrodes. TiO2/AC powders were prepared by one-step vapor hydrolysis of TiCl4 with active carbon. The structure and composition of the powders were analyzed by means of XRD and FTIR, and the results showed that anatase titanium dioxide of particle size 16.5 nm was produced after calcination at 400 °C. The influences of the preparative parameters of the air electrode on its discharge performance were studied by polarization curve measurements. The terminal voltage of the air battery was maintained at above 1.05 V while the current density of the air electrodes reached 150 mA cm-2. These results show that the composite catalyst has high electrochemical activity for the oxygen reduction reaction.
