Abstract

We report improved photo-catalytic properties of single-crystalline $TiO_2$ nanowires surrounded by Pt cubes for methanol electrooxidation under UV illumination. The $TiO_2$-Pt consists of single-crystalline $TiO_2$ nanowires grown along [0 0 1] direction and Pt cube nanoparticles with dominantly exposed {1 0 0} facets confirmed by transmission electron microscopy images and fast Fourier transform patterns. The nanostructure electrode consisting of $TiO_2$ nanowires and Pt cubes exhibits a remarkably improved performance for methanol electrooxidation in acid solution as compared to that of $TiO_2$ nanowires.
