報告內容摘要

Bi2WO6 was synthesized via solvothermal method with different solvents. The precursors of Bi and W were Bi(NO3)3·5H2O and Na2WO4·2H2O, respectively. The solvents were water and ethylene glycol (EG) and the prepared Bi2WO6 photocatalysts were denoted as EG0 and EG70, respectively. The surface characteristics of Bi2WO6 were analyzed by X-ray diffraction (XRD), UV-Vis diffusion reflectance spectrophotometry (UV-Vis-DRS), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and BET surface area analysis. The photocatalytic activity of Bi2WO6 was evaluated by decolorizing C.I. Reactive Red 2 (RR2) under visible-light irradiation (λ > 420 nm). The average diameter, BET surface area, pore volume, pore width and band gap of EG0 were 17.5 nm, 24.2 m2/g, 0.14 cm3/g, 23.2 nm and 2.8 eV, respectively; and those of EG70 were 4.7 nm, 100.8 m2/g, 0.28 cm3/g, 11.1 nm and 2.9 eV, respectively. The photodegradation rate constants (k) of RR2 fitted pseudo-first-order kinetics and the k values of EG0 and EG70 were 0.174 and 1.644 hr-1, respectively.
