| Abstract | N-doped BiVO4 photocatalysts (CS-BiVO4-xN) were successfully prepared by Sol-Gel method taking the corn stem as template and C6H12N4 as N source. The samples were characterized with X-ray diffraction (XRD), X-ray photoelectron spectroscope (XPS), scanning electron microscope (SEM), Fourier infrared spectrum (FTIR), and UV-Vis absorption spectroscope (UV-Vis). The photocatalytic activity were investigated by degradation of methyl oran ge (MO) under visible-light irradiation. The results showed that N doping did not change the crystallinity of the BiVO4. The doped N replaced some of O atoms in BiVO4 and formed the -N-V-O band. The synergetic effect of impurity energy levels and oxygen vacancies led to narrower band-gap and red-shift of optical absorption band. Furthermore, the N doped BiVO4 with honeycomb like structure and smaller crystal sizes was prepared by using corn stem as template, which is beneficial to higher initial MO absorption and better photocatalytic activity. The degradation rate of MO under visible light illumination for 50 min is 80.9% in presence of CS-BiVO4-12N, which is much higher than those in presence of CS-BiVO4 (25.56%) and BiVO4-12N (28.34%). |
