報告內容摘要
In this work, BiVO4 was synthesized using a one-step hydrothermal method. The precursors of Bi and V were Bi(NO3)3·5H2O and NH4VO3, respectively. The photocatalytic activity of BiVO4 was evaluated by using it to decolorize C.I. Reactive Red 2 (RR2) under ultraviolent (UV) or visible light (Vis.) irradiation. The surface characteristics of BiVO4 were analyzed by X-ray diffraction (XRD), UV-Vis diffusion reflectance spectrophotometry (UV-Vis-DRS) and scanning electron microscopy (SEM). The mean diameter and band gap of BiVO4 particles were 23 nm and 2.4 eV, respectively. After 180 min of reaction, the degrees of RR2 decolorization by BiVO4 adsorption, Vis./BiVO4 and UV/BiVO4 were 10%, 46% and 85%, respectively. The photodegradation rate constants (k) of RR2 fitted pseudo-first-order kinetics and the k values of the Vis./BiVO4 and UV/BiVO4 systems were 0.0025 and 0.0096 min-1, respectively.
