We report an enhanced, visible light, photocatalytic activity for TiO₂ doped with multiple dopants like Ga, N and S. The pristine and doped TiO₂ nanoparticles exist as anatase phase of TiO₂ having a particle size of 12e15 nm. Improved visible light absorption is seen for N, S and Ga, N, S tri-doped TiO₂ and the highest visible light absorption is observed for GaNSeTiO₂. XPS analysis shows the presence of bonded S and N (N-Ti-O, S-Ti-O) in the sample. Photocatalytic activity of the samples of TiO₂ were evaluated  for the degradation of methyl orange (MO) in visible light and GaNS-TiO₂ exhibits the highest activity. The enhanced activity of GaNS-TiO₂ is attributed to a combination of factors like creation of defect level within the bandgap of TiO₂, enhanced lifetime of photogenerated charge carriers and increased photoresponse. Addition of quenchers like benzoquinone (BQ) and 2-propanol results in the 21% and 17% decrease in photodegradation of MO indicating that the O₂^-. and OH• are the predominant active species in the visible light, photodegradation of MO, using GaNS-TiO₂.
