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.
