Abstract

Different Ti/(I/S) composites are synthesized by sol‐gel method. The microstructure, interfacial and optical properties of the obtained different Ti/(I/S) composites are characterized by scanning electron microscope (SEM), transmission electron microscope (TEM), X‐ray diffraction (XRD), surface area measurement (BET), and UV–vis diffused reflectance spectroscopy (UV‐Vis DRS). The results show that 5‐Ti/(I/S) composite has an obvious photocatalytic activity to rhodamine B (RhB) and the degradation rate can reach 81%, ·O2− is the key oxidative species. Moreover, 5‐Ti/(I/S) composite has good stability and repeatability.

TiO2柱状伊利石/蒙脱石(Ti/(I/S))在可见光下光催化降解罗丹明B

采用溶胶-凝胶法合成了不同的Ti/(I/S)复合材料。采用扫描电镜(SEM)、透射电镜(TEM)、X射线衍射(XRD)、表面积测量(BET)和紫外-可见漫反射光谱(UV - Vis DRS)对不同Ti/(I/S)复合材料的微观结构、界面和光学性能进行了表征。结果表明，5‐Ti/(I/S)复合材料对罗丹明B (RhB)具有明显的光催化活性，降解率可达81%，O2−是关键氧化物质。此外，5‐Ti/(I/S)复合材料具有良好的稳定性和重复性。

期刊介绍： The journal Crystal Research and Technology is a pure online Journal (since 2012). Crystal Research and Technology is an international journal examining all aspects of research within experimental, industrial, and theoretical crystallography. The journal covers the relevant aspects of -crystal growth techniques and phenomena (including bulk growth, thin films) -modern crystalline materials (e.g. smart materials, nanocrystals, quasicrystals, liquid crystals) -industrial crystallisation -application of crystals in materials science, electronics, data storage, and optics -experimental, simulation and theoretical studies of the structural properties of crystals -crystallographic computing
