Sn doped TiO2 nanotube with oxygen vacancy for highly efficient visible light photocatalysis

Sn doped TiO2 nanotube with oxygen vacancy (Vo-SnTiO2) was successfully synthesized via a facile hydrothermal process and subsequent annealing in nitrogen atmosphere. The morphology, structure and photocatalytic performance of Vo-SnTiO2 in the degradation of nitrobenzene were characterized by scanning electron microscopy, transmission electron microscopy, X-ray diffraction, Raman spectroscopy, X-ray photoelectron spectroscopy, UV–vis absorption...
