Preparation of Bi2O3/TiO2 fixed photocatalysts and degradation of aqueous Bisphenol A under simulated sunlight
Journal Title: Scientific Journal of Environmental Sciences - Year 2016, Vol 5, Issue 9
Abstract
A series of Bi2O3/TiO2 composite photocatalysts (T, 0.5BT, 1.0BT, 2.0BT, 4.0BT, 6.0BT and 8.0BT) were synthesized and used to degrade aqueous bisphenol A (BPA) under simulated sunlight irradiation. The structures of the photocatalysts were extensively characterized using X-ray diffraction (XRD) and UV-visible diffuse reflectance spectroscopy (UV-vis DRS). UV-visible spectral analysis indicated that all of the Bi2O3/TiO2 photocatalysts shifted their absorption band toward visible light, and reduced energy gap. The experimental results indicated that aqueous BPA with a Bi-Ti atomic ratio of 4:96 was the most effective in degrading BPA under simulated sunlight irradiation.
