摘要:
采用富有粘附特性的儿茶酚结构修饰蔗渣表面，为纳米TiO2粒子生成提供附着位点，制备稳固型蔗渣@TiO2复合材料。通过X射线衍射仪（XRD）、傅立叶变换红外光谱仪（FTIR）和扫描电镜（SEM）对复合材料的化学结构和表面形态进行分析，并研究了其光催化性能。XRD表明儿茶酚修饰的蔗渣表面生成了锐钛矿型TiO2纳米粒子，且粘附稳固性提高，FTIR及SEM表明蔗渣表面成功负载纳米TiO2粒子，粒径约为200 nm，光催化研究表明，所制备的蔗渣@TiO2复合材料具有良好的光催化性能，且在紫外光下催化效果好。
Abstract:
The surface of bagasse was modified with catechin structure with adhesive properties to provide adhesion sites for the generation of nano TiO2 particles, and the stable bagasse @TiO2 composite was prepared. The chemical structure and surface morphology of the composites were analyzed by X-ray diffraction (XRD), fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM), and the photocatalytic properties of the composites were also studied. XRD showed that anatase TiO2 nanoparticles were formed on the surface of bagasse modified by catechol, and the adhesion stability was improved. FTIR and SEM showed that nano TiO2 particles were successfully loaded on the surface of bagasse, and the particle size was about 200 nm. The photocatalytic study showed that the prepared bagasse @TiO2 composite had good photocatalytic performance and good catalytic effect under ultraviolet light.
