Wang, Bangda Zhou, Yuexi Li, Lei Xu, Hui Sun, Yinglong Du, Yunsan Wang, Yi In Situ Synthesis of TiO<sub>2</sub>‑Doped Mesoporous Silica from Coal Fly Ash for the Photocatalytic Degradation of Dyes TiO<sub>2</sub>-doped mesoporous silica (TDMS) was synthesized in situ from coal fly ash for photocatalytic degradation of organic dyes. The prepared TDMS is mainly composed of SiO<sub>2</sub> and anatase TiO<sub>2</sub> and has a sponge-like mesoporous structure with a high specific surface area of 297 m<sup>2</sup>/g. In photocatalytic experiments, TDMS shows good performance in the removal of dyes. The decoloration rates of both rhodamine B and acid orange II reached 99.9% within 6 h at a TDMS dosage of 4 g/L, and the total organic carbon (TOC) removal efficiency reached 90.3 and 84.1%, respectively. Furthermore, whereas the dye decoloration rate of TDMS is comparable to that of commercial TiO<sub>2</sub> (anatase), it shows much better TOC removal efficiency. The results indicate that TDMS can be a potential and low-cost photocatalyst for treating water polluted with dyes. surface area;TOC removal efficiency;TDMS dosage;dye decoloration rate;mesoporous silica;decoloration rates;photocatalytic degradation;rhodamine B;Photocatalytic Degradation;II;photocatalytic experiments;sponge-like mesoporous structure;SiO 2;removal efficiency;anatase TiO 2;6 h;Dyes TiO 2;Situ Synthesis;TiO 2 2018-10-30
