Zn-3(VO4)(2) nanorods with visible light-driven photocatalytic activity were prepared by hydrothermal reaction and characterized by x-ray diffraction, Fourier transform infrared, scanning electron microscopy, x-ray photoelectron spectroscopy, UV-vis diffuse reflectance spectra, and Brunauer-Emmett-Teller surface area and pore size analyzer. The Zn-3(VO4)(2) nanorods consisted of rods with a thickness of approximately 30 nm, length in the range 400-600 nm, and width in the range 150-250 nm. The photocatalytic degradation activities for methylene blue (MB) and 4-nitrophenol (4-NP) over the Zn-3(VO4)(2) nanorods were studied in detail. The photocatalytic activity of the as-prepared photocatalyst for MB and 4-NP in visible light under the same conditions was about 3.5 times and 2.5 times higher than that of N-TiO2, respectively. The main active species in the photodegradation come from center dot OH, and the photogenerated electrons also partly involved in the photocatalytic degradation process, in which the center dot OH radicals formed were in proportional to the light illumination time obeying zero-order reaction rate kinetics.
