Abstract
The nanoTiO2-CNT-Pt on Ti substrate complex electrodes were prepared from precursor of (Ti(OEt)4) directly hydrolyzed and by cyclic voltammograms electroplating method . The XRD and SEM results showed that the nano TiO2 (anatase) particle sizes ranged 5~10 nm and the Pt nanoparticle (average size 9nm) dispersed uniformly on nanoTiO2-CNT film surface. The electrocatalytic activity of Ti/nanoTiO2-CNT-Pt electrode was investigated by cyclic voltammetry and chronopotentiogram. The results indicated that the Ti/nanoTiO2-CNT-Pt electrode exhibited very high electrocatalytic activity and stability for the electro-oxidation of methanol at room temperature. When Pt loading was 0.32 mg/cm2, the oxidation peak current of methanol was 480 mA/cm2.
