3d过渡金属掺杂TiO2纳米晶膜电极的光电化学研究
Photoelectrochemical Behavior of 3d Transition Metal Nanostructured film Electrode Doped with TiO2
摘要
Abstract
The 3d transition metal ions [Cr(Ⅲ), Fe(Ⅲ), Mn (Ⅱ), Co(Ⅱ), Ni(Ⅱ), Cu(Ⅱ), Zn(Ⅱ)]nanocrystalline doped with TiO2(abbr. M3d-TiO2) were characterized by AFM and XRD. The M3d-TiO2 nanostructured film electroede was prepared and investigated with photoelectrochemical techniques. The results show that the size of M~-TiO2 nanocrystalline particles was quite uniform and the radii were about 15 nm. The M3d-TiO2 nanocrystalline particles were a mixture of brookite and anatase crystal forms. Of all the M3D-TiO2 investigated in this paper, however, the photocurrent intensity of Zn2+-TiO2 nanostructured film electode was higher than that of the electrode undoped with TiO2. The phenomenon of p-n type inversion was observed in certain wavelength range, which was caused by 3d transition ions doping.关键词
