Study on the Preparation and Photocatalytic Property of N, Fe, Zn Nano-TiO2 Loaded on Active Carbon
In the paper, tetranbutyl titanate was loaded on granular active carbon using sol-gel dip-coating technique to form anatase nano-TiO2 photocatalyst with an average diameter of 16nm doped with N, Fe, Zn ions. The morphology and crystal structure were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and UV–Vis spectrophotometer, respectively. The results show that the prepared photocatalyst demonstrates outstanding photodegradation efficiency and light response zone has transferred from ultraviolet light zone to UV-visible zone. Moreover, considering methylene blue (MB) as target degradation pollutant, under visible light irradiation, the photodegradation rate reached beyond 100% after 1h.
