摘要
自组装制备出TiO_2-蒙脱石纳米材料,采用BET和UV-Vis DRS表征手段对材料比表面积及禁带宽度进行分析,通过表面酸碱滴定实验分析材料表面反应,并通过光催化实验研究分析材料的光催化降解性能。结果表明:TiO_2-蒙脱石在滴定过程中发生质子化合脱质子化反应,其对MB的光催化降解率达65.46%,降解性能良好。
In this study, TiO2-montmorillonite nanomaterials were prepared by self-assembly. The specific surface area and band gap of the material were analyzed by BET and UV-Vis DRS characterization. The surface reaction of the material was analyzed by surface acid-base titration experiment and passed the photocatalysis experiment. Study and analyze the photocatalytic degradation properties of materials. The results show that the protonation deprotonation reaction occurs in the titration process of TiO2-montmorillonite, and the photocatalytic degradation rate of MB is 65.46%, and the degradation performance is good.
