英文摘要	Pt/nanoTiO(2)-CNT complex catalysts were prepared by direct hydrolysis of Ti(OEt)(4) and electrochemical scan electrodepositing method. The results of XRD and SEM showed that the nanoTiO(2) (anatase) and Pt nanoparticles (size about 5 similar to 10 nm) were dispersed uniformly on CNT film surface. The electrocatalytic activity of Pt/nanoTiO(2)-CNT electrode was investigated by cyclic voltammetry and chronopotentiogram. The results indicated that Pt/nanoTiO(2)- CNT electrode (Pt loading was 0.32 mg . cm(-2)) exhibited high electrochemical activity surface area (51.8 m2. g(-1)) and very high electrocatalytic activity and stability for the electro-oxidation of ethanol at room temperature in atmosphere pressure. The oxidation peak potentials of ethanol were 0.59, 0.96, and 0.24 V, and the corresponding oxidation peak current sdensities were - 115, -113, and -75 mA . cm(-2). The high electrocatalytic activity and good stability can be attributed to the synergistic catalytic effect among nanocomposite.
