摘要/Abstract

摘要：

采用一步水热法成功制备鳞状形貌的BiOBr/Bi₂WO₆复合物，通过X射线衍射（XRD）仪、扫描电子显微镜（SEM）、N2吸附/解吸附比表面测定仪（BET）、傅里叶变换红外（FT-IR）光谱等对复合物进行了表征。对比Bi₂WO₆与BiOBr的SEM照片，结合KBr的浓度实验，提出了BiOBr/Bi₂WO₆的鳞状形貌的形成机理。选取有机染料为吸附质，BiOBr/Bi₂WO₆为吸附剂进行了复合物吸附性能测试。结果表明，BiOBr/Bi₂WO₆对阳离子染料表现出优越的吸附性能，10 min对次甲基蓝（MB）的吸附率高达99%，优于常规的活性炭吸附剂。此外，BiOBr/Bi₂WO₆对有机染料的吸附行为符合准二级反应速率方程和Freundlich等温吸附模型。

Abstract:

BiOBr/Bi₂WO₆ with squamous morphology is successfully prepared by a one-step hydrothermal method. BiOBr/Bi₂WO₆ is shown to be an ideal material for adsorption. The structure of BiOBr/Bi₂WO₆ is characterized by powder X-ray diffraction (XRD), X-ray photoelectron (XPS) spectroscopy, and Fourier transform infrared (FT-IR) spectroscopy, and the morphology is observed with scanning electron microscopy (SEM). The specific surface of BiOBr/Bi₂WO₆ is tested by a nitrogen adsorption/desorption surface area pore size distribution analyzer. According to the experiments with different concentrations of KBr and the SEM photos of BiOBr and Bi₂WO₆, the possible morphology formation mechanism of squamous BiOBr/Bi₂WO₆ is proposed. We design a series of adsorption experiments and test the adsorption properties of the compounds with organic dyes as adsorbent and BiOBr/Bi₂WO₆ as adsorbent. The results show that BiOBr/Bi₂WO₆ exhibits a higher adsorption capacity for cationic dyes, especially the adsorption rate of MB, and BiOBr/Bi₂WO₆ shows a higher adsorption capacity compared with that of activated carbon. Adsorption behavior of BiOBr/Bi₂WO₆ is consistent with the Freundlich isotherm model and the adsorption process of MB follows a pseudo-second-order kinetic model.
