Pt is one of the most important electrode materials employed in direct methanol fuel cell, and many efforts have been directed to improving its electrocatalytic performance. In this work, PteTiO 2 nanocomposites are successfully prepared by a solegel method. As revealed by TEM, Pt nanoparticles with
Pt nanoparticles on TiO 2 nanorod arrays have been prepared and used for the electrooxidation of ethanol in acidic and alkaline media. The vertically aligned TiO 2 nanorod arrays provide a three-dimensional frame for supporting Pt nanoparticles. FESEM and TEM show that the Pt nanoparticles about 3 n
