空心球状碘氧化铋的制备及其对染料的吸附降解性能
Preparation of Hollow Spherical Bismuth Oxyiodide and ItsAdsorption and Photocatalytic Degradation of Dyes
摘要
Abstract
Hollow spherical bismuth oxyiodide(BiOI) was synthesized via the solvothermal method.The as-prepared BiOI was well characterized by X-ray diffraction(XRD), scanning electron microscopy(SEM) and N2 adsorption-desorption analysis.Two different types of dyes, such as cationic rhodamine B(RhB) and anionic reactive blue KN-R, were selected to evaluate the adsorption and photocatalytic activity of BiOI.The results show that the initial pH values have great effect on the adsorption and degradability of different types of dyes.The degradation efficiency of RhB and KN-R reaches 96.2% and 92.5%, respectively.The active species trap experiments reveal that h+ is the dominant specie for the degradation of dyes.关键词
