“…Outra vantagem obtida da dopagem de TiO 2 com TRs é a melhoria na atividade fotocatalítica do TiO 2 . Em particular, a dopagem do TiO 2 com Sm [48], Tb [49], [50] e Tm [51] tem se mostrado uma boa estratégia para aprimorar a atividade fotocatalítica do TiO 2 , onde o Sm se destaca dentre os demais para esta finalidade [52]. A co-dopagem também é reportada como tática para aprimorar a atividade catalítica do TiO 2 [53]- [56].…”

A series of tungsten‐doped Titania photocatalysts were synthesized using a low‐temperature method. The effects of dopant concentration and annealing temperature on the phase transitions, crystallinity, electronic, optical, and photocatalytic properties of the resulting material were studied. The X‐ray patterns revealed that the doping delays the transition of anatase to rutile to a high temperature. A new phase WyTi1‐yO2 appeared for 5.00 wt% W‐TiO2 annealed at 900 °C. Raman and diffuse reflectance UV–Vis spectroscopy showed that band gap values decreased slightly up to 700 °C. X‐ray photoelectron spectroscopy showed that surface species viz. Ti3+, Ti4+, O2−, oxygen‐vacancies, and adsorbed OH groups vary depending on the preparation conditions. The photocatalytic activity was evaluated via the degradation of methylene blue using LED white light. The degradation rate was affected by the percentage of dopants. The best photocatalytic activity was achieved with the sample labeled 5.00 wt% W‐TiO2 annealed at 700 °C.
