The TiO2/Skeleton, TiO2/Dens and TiO2/HAP composites were prepared by sol–gel method. X-ray diffraction (XRD) and scanning electron microscope (SEM) were carried out to characterize them. Their photocatalytic activities were evaluated by degradation of Acid Red B under solar light irradiation. The results showed that the photocatalytic activity of the TiO2 catalyst can be greatly enhanced by using appropriate amount of loaded biomaterials or biomimetic material. Otherwise, the influencing factors, such as TiO2 loaded content, heat-treated temperature and heat-treated time on the photocatalytic activity of TiO2/Skeleton, TiO2/Dens and TiO2/HAP were reviewed. Meanwhile, the effect of solar light irradiation time and dye initial concentration on the photocatalytic degradation of Acid Red B dye in aqueous solution were also investigated in detail.
The TiO2/Skeleton (a), TiO2/Dens (b) and TiO2/HAP (c) composites were prepared and photocatalytic activities were evaluated by degradation of Acid Red B under solar light irradiation. The results showed that the photocatalytic activity of the TiO2 catalyst can be greatly enhanced by using appropriate amount of loaded biomaterials or biomimetic material.Figure optionsDownload high-quality image (123 K)Download as PowerPoint slide
