摘要：

This study focuses on the removal of the methyl orange (sodium p-dimethyl amino azo benzene sulfonate) of a representative dye compound in a liquid photo-system using nanometer-sized Zn-incorporated TiO(2) Synthesized by a solvothermal method. The Zn-incorporated TiO(2) particles exhibited a mixed structure of anatase of TiO(2) and ZnTiO(3) with a particle size of below 20 nm. The absorbance was shifted to the higher wavelength on 2.0 mol% Zn-incorporated TiO(2) Compared to pure TiO(2). In the XRD pattern, the structure of ZnTiO(3) was seen at 2 theta = 31.75. The XPS result of O 1s confirmed that 2.0 mol% Zn-TiO(2) had a higher hydrophilic property (Me-OH/Me-O = 0.46) than pure TiO(2) (Me-OH/Me-O = 0.25) did. Based on these results, the photodecomposition for methyl orange in liquid reaction was enhanced over Zn-incorporated TiO(2) compared with pure TiO(2): methyl orange of 10 ppm was completely decomposed after 120 min over 2.0 mol% Zn-incorporated TiO(2).
