Photocatalytic Activities

In order to restrain the recombination of electron-hole pairs of photocatalysis and induce the absorption spectra to shift to the visible region, TiO2nanowire arrays doped with different transition metal ions were prepared by sol-electrophoresis deposition method. The photocatalytic activities of all doped nanowire arrays (M/TiO2) were measured under visible light. Transition metal ions (Fe3+, Zn2+, Cr3+and Cu2+) were chosen as doping ions. The best doping content of each ion was found via photocatalytic degradation of methyl orange solution under visible light, there are 0.5 wt% Fe3+，1.0 wt% Zn2+，0.5 wt% Cr3+and 0.25 wt% Cu2+respectively. Under the best doping content of each ion for M/TiO2nano-arrays, the photocatalytic activities are Fe>Zn>Cu>Cr. The effect mechanisms are discussed from different views of doped semiconductor and surface oxygen absorption.
