采用简单的控制水解法合成了介孔SiO2纳米结构。所制备的介孔SiO2纳米结构由无定形二氧化硅纳米颗粒组成，具有显著的光诱导吸附性能。光诱导的吸附增强可能是由于羟基与染料分子之间的交换吸附引起的，因为在光照射下的吸附过程表现出显着的化学吸附性质。将该介孔SiO2和金红石型TiO2材料复合，由于TiO2纳米结构具有良好的吸附性能和表面缺陷的增加，所得复合光催化剂对RhB染料的光催化降解性能表现出上级优势。这些结果为进一步设计和开发具有实际应用价值的高性能光催化剂提供了新奇的思路。
Mesoporous SiO2nanostructure was synthesized by a simple controlled hydrolysis process. The obtained mesoporous SiO2nanostructure was composed of amorphous silica nanoparticles and exhibits significant light-induced adsorption performance. The light-induced adsorption enhancement may be caused by exchanging adsorption between hydroxyl groups and dye molecules because the adsorption process under light irradiation exhibits significant chemical adsorption property. Combining this mesoporous SiO2and rutile TiO2materials, the obtained hybrid photocatalyst displays superior photocatalytic degradation performance of RhB dye due to the excellent adsorption performance and the increase of surface defects on the surface of TiO2nanostructure. These results provide novelty route for the further design and development of high performance photocatalyst in actual application.
