Effect of Double Elements Co-Doping on Nano-TiO₂ Photocatalysis of Rhodamine B Solution

Abstract:

Hydro-thermal method was applied to synthesize nanoTiO₂ particles doped with metal and non-metallic elements. nanoTiO₂ particles were doped at different calcinations temperatures with S and Fe, Ce and La, respectively. X-ray diffraction results indicated that the minimum diameter of nanoTiO₂ doped with Ce and S was about 7.2nm, which is smaller than other type of double-element doped nanoTiO₂. In addition, with the increase of calcinations temperature, the size of nanoTiO₂ particle increased and the diameter of nanoTiO₂ doped with Fe and S was the most obvious one. Rhodamine B was used to simulate the pollutant to analyze the photocatalytic property of doped nanoTiO₂. The results indicated that the degradation rate of rhodamine B by nanoTiO₂ doped with La and S under the calcinations temperature of 450 °C reached66.22%.
