Morphology And Structure

Wormhole-shaped F-doped TiO2/Ti photoelectrodes were prepared by microarc oxidation method in NaF solution. The morphology and structure of the photoelectrodes were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD) and X-ray fluorescence (XRF). It was found that F-doped TiO2/Ti photoelectrodes were porous and composed of anatase TiO2. The photocatalytic properties of F-doped TiO2/Ti photoelectrodes were investigated by photodiscoloration rate of Rhodamine B(Rh.B) under different conditions. All results showed that the photoelectrodes prepared at voltage of 160V, NaF concentration of 0.01mol/L and oxidation time of 10min have optimal photocatalytic performance. Rh.B was almost completely removed by F-doped TiO2/Ti photoelectrodes after 120min under the illumination of artificial visible light.

Novel visible-light responded aluminosilicophosphate-5 (SAPO-5)/g-C3N4 composite has been easily constructed by thermal polymerization for the mixture of SAPO-5, NH4Cl, and dicyandiamide. The photocatalytic activity of SAPO-5/g-C3N4 is evaluated by degrading RhB (30 mg/L) under visible light illumination (λ > 420 nm). The effects of SAPO-5 incorporation proportion and initial RhB concentration on the photocatalytic performance have been discussed in detail. The optimized SAPO-5/g-C3N4 composite shows promising degradation efficiency which is 40.6% higher than that of pure g-C3N4. The degradation rate improves from 0.007 min−1 to 0.022 min−1, which is a comparable photocatalytic performance compared with other g-C3N4-based heterojunctions for dye degradation. The migration of photo-induced electrons from g-C3N4 to the Al site of SAPO-5 should promote the photo-induced electron-hole pairs separation rate of g-C3N4 efficiently. Furthermore, the redox reactions for RhB degradation occur on the photo-induced holes in the g-C3N4 and Al sites in SAPO-5, respectively. This achievement not only improves the photocatalytic activity of g-C3N4 efficiently, but also broadens the application of SAPOs in the photocatalytic field.
