TiO_2光敏化研究进展

TiO_2 Photosensitization Research Progress

光敏化是延伸TiO2激发波长范围的主要途径之一,通过添加适当的光活性敏化剂,使其以物理或化学吸附于TiO2表面,扩大了TiO2激发波长的范围,使之能充分利用可见光。常见敏化剂有无机敏化剂、纯有机染料、金属有机配合物和复合敏化剂。文章综述了近些年来TiO2光敏化的研究进展与前景展望。

The photosensitization is one of main ways to expand TiO2 execited-wavelength range. By adding suitable photoactive sensitizers which adsorb on the TiO2 surface by physical or the chemical methods, expand the TiO2 excitde-wavelength range, enable it to use the visible light fully. The common sensitizers are inorganic sensitizer, pure organic dye, organometallic complex and compound sensitizer, recent progress in the TiO2 photosensitization research were reviewed and the prospect forecast was discussed.
