摘要/Abstract

摘要：

以醋酸铜为原料, 交联累托石(CN-REC)为载体和模板, 制备了CN-REC /Cu₂O纳米复合材料. 利用X射线衍射(XRD)、透射电镜(TEM)、傅里叶变换红外(FTIR)光谱、紫外-可见漫反射光谱(UV-Vis DRS)等技术对复合材料的形貌、表面结构、层间微结构、光响应性能进行了研究. 结果表明: CN-REC对Cu₂O的形貌具有较好的调控作用, Cu₂O均匀分散负载于CN-REC的层间和片层表面; Cu₂O和CN-REC通过Si―O―Cu键发生相互作用; 复合材料的能带隙变宽、光响应能力增强. 以卤素灯为可见光光源, 活性艳红(X-3B)为目标污染物, 研究了复合材料的可见光催化性能, 结果表明, 光催化反应过程符合L-H动力学模型, 2 h内浓度为160 mg·L^-1的X-3B去除效率可超过80%.

关键词: 交联累托石, Cu₂O, 纳米复合材料, 可见光催化活性

Abstract:

CN-REC/Cu₂O nanocomposites were synthesized with Cu(CH3COO)2·H₂O as a copper source and cross-linked sodium rectorite (CN-REC) as a carrier and template. The obtained samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy, and ultraviolet visible diffuse reflectance spectrum (UV-Vis DRS). The results indicate that the regulatory effects of CN-REC on Cu₂O are significant. Cu₂O is dispersed in the interlayer and on the surface of?the lamellar structure of CN-REC. A Si―O―Cu bond was formed between the cuprous oxide crystal and the CN-REC crystal, which established a bridge for the transfer of photogenerated charge. The energy band gap of the nanocomposites became wider and the photoresponse properties of the nanocomposites became stronger. To study the visible light photocatalytic activity of the nanocomposites, reactive brilliant red (X-3B) was selected as a target contaminant. The photocatalytic degradation rate of X-3B with the nanocomposites is more than 80%, which is better than that with Cu₂O. The degradation progress accorded with the L-H kinetics equations.
