Novel preparation of carbon-TiO2 composites

- Glycerol and TiOSO4·xH2O produced a carbon-anatase precursor in a one-step sol-gel reaction.
- Ultrasound irradiation led to the formation of crystalline TiO2 prior to thermal treatment.
- Carbon and TiO2 nanocrystals developed larger specific surface in composites.
- Large band gap (3.6 eV) in TiO2 was obtained.
- Benzenesulfonic acid identified by LC-MS among decomposition reaction intermediates of the dye Acid Orange 7.
