Abstract

Brush-like ZnO/TiO2 core-shell nanostructures have been prepared by a two-step route combined with hydrothermal method and magnetron sputter. Electronic properties of these interesting nanostructures were investigated by both photoelectron spectroscopy and X-ray absorption. Near edge X-ray absorption were measured by total electron yield mode and fluorescence mode. The two different modes showed different spectra, which were attributed to the different penetration depths and the self-absorption effect in the fluorescence mode. The experimental findings suggest the brush-like nanostructures should offer significant potential in photocatalysis applications.
