CoTMPP-TiO 2 NT/BP composites have been synthesized by preparing CoTMPP and depositing CoTMPP on carbon-supported titania nanotube (TiO 2 NT/BP) using microwave irradiation method at the same time, followed by heat-treatment from 300 to 900°C in N 2 atmosphere. The catalytic activity for oxygen reduction was evaluated by rotating disc electrode technique in half cells with 0.5M H 2 SO 4 . The number of electrons exchanged during ORR and the percentage of peroxide (%H 2 O 2 ) produced by the reaction were evaluated for catalysts by rotating ring disk electrode (RRDE) measurements. The influences of TiO 2 NT doping, the heat-treating temperature and the different ratios of BP:TiO 2 NT on the activity of electrocatalysts for oxygen reduction were investigated. The stability of the CoTMPP-TiO 2 NT/BP electrocatalysts was studied with potentialstatic-polarization measurements in 0.5M H 2 SO 4 +0.5M CH 3 OH. CoTMPP-TiO 2 NT/BP composites show higher catalytic activity and better stability than CoTMPP/BP. The mechanism for the enhanced catalytic activity of CoTMPP-TiO 2 NT/BP is discussed.
