Abstract

Nano-TaO_x particles were supported on multi-walled carbon nanotubes via the thermal decomposition of oxy-tantalum phthalocyanine. The phthalocyanine-derived carbon connected TaO_x particles with the nanotube-support to provide a conductive path. The oxygen reduction reaction activity, which solely originated from TaO_x, was above 0.9 V with larger currents than conventional TaO_x particles in acidic media.
