Preparation, Characterization And Electrochemical Properties Of Nano Tio_(2)-Cnt-Pt On Ti Substrate Complex Electrode, Dao-Bao Chu
Journal of Electrochemistry
The nanoTiO_(2)-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 TiO_(2) (anatase) particle sizes ranged 5~10 nm and the Pt nanoparticle (average size 9nm) dispersed uniformly on nanoTiO_(2)-CNT film surface. The electrocatalytic activity of Ti/nanoTiO_(2)-CNT-Pt electrode was investigated by cyclic voltammetry and chronopotentiogram. The results indicated that the Ti/nanoTiO_(2)-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/cm~(2), the oxidation peak current of methanol was 480 …
