Mesoporous TiO(2) microspheres were prepared by a hydrothermal reaction and are characterized in this paper. Decoloration and mineralization during photodegradation of Orange II by mesoporous TiO(2) at different pH values, formation of sulfate, relative luminosity to luminous bacteria and recycling experiments of the catalyst were studied. The FTIR results further suggested that the novel mesoporous TiO(2) can not only decolor and mineralize dyes completely but also can be effectively reused several times. On the basis of the research, mesoporous TiO(2) would be a promising photocatalyst for practical use.
通过水热反应制备了介孔TiO₂微球，并在本文中对其进行了表征。研究了介孔TiO₂在不同pH值下光降解橙黄II过程中的脱色和矿化、硫酸盐的形成、对发光细菌的相对发光度以及催化剂的循环实验。傅里叶变换红外光谱（FTIR）结果进一步表明，新型介孔TiO₂不仅能使染料完全脱色和矿化，还能有效重复使用多次。基于该研究，介孔TiO₂将是一种有实际应用前景的光催化剂。
