We report the synthesis of carbon coated and sulfur doped titania nanoparticles using a continuous, single-step laser pyrolysis technique. We employed air as oxidant and C 2 H 4 as laser energy transfer agent (sensitizer)/carbon donor, both carrying the TiCl 4 vapors as a titania precursor. The volatile (CH 3 ) 2 S 2 was used to introduce sulfur as dopant in the nanopowders. The incorporation of C and S atoms in nanopowders with anatase dominant phase and with average particle diameter between 18 and 25nm was performed through the addition of S 2 (CH 3 ) 2 and C 2 H 4 to the reactive precursor mixtures. The samples were characterized by: EDX, XRD, TEM, XPS and UV–Vis spectroscopy. By the introduction of the sulfur precursor, the anatase-to-rutile ratio within the resulted TiO 2 -based nanoparticles decreased, as well as their bandgap energy values which are also lower than those of commercial TiO 2 Degussa P25.
