Enhanced charge separation efficiency of sulfur-doped TiO2 nanorod arrays for an improved photoelectrochemical glucose sensing performance

Modulation of titania nanoflower arrays transformed from titanate nanowire arrays to boost photocatalytic Cr(vi) detoxification

“…N and S doping can reduce the bandgap of TiO 2 and decrease the recombination rate of the photoinduced electron–hole pairs. 48 The NW and NF-0 show the same valence states for the Ti and O elements, and a small amount of nitrogen doping (Fig. S3 and S4, ESI†).…”

“…6c), suggesting its remarkable stability and reusability. The excellent photocatalytic activity of NF-50 is ascribed to the double advantages: (1) S and N co-doping reduces the band gap and improves the separation efficiency of photogenerated carriers, 48 which still needs further investigations in the future; (2) the anatase/rutile junction further promotes the photogenerated carrier separation. 36…”

Vapor Deposition-Assisted Sulfurization Synthesis of S-doped WO3 Nanorods and Their Enhanced Photoactivity

“…The S doping into TiO 2 increases the charge-transfer rate while inhibiting the recombination of photogenerated electrons and holes, which considerably improve the photoelectric catalytic efficiency of the pristine TiO 2 . 51 Furthermore, in the chemical vapor deposition derived S-doped ZnO, the S doping induces the modulation of electronic band structure with concomitant improvement in ZnO's electrical conductivity. The S-doped formulation triggers the formation of more charge carriers and more efficient transport of photogenerated electrons, resulting in the enhancement of PEC efficiency than that of the pristine ZnO.…”
