摘要:二氧化钛具有光催化的性质,在生产和生活中具有很高的价值,且具有很高的光降解效应,因此在催化方面广受人们的青睐,而且凭借着其成本低,无毒,易制取,操作方便而成为光催化剂中的新宠,由它的这些优点,因此具有很高的光降解方面的研究以及实用价值。本文着重探讨了二氧化钛的制备过程以及其它的光催化性能,对于实验所得的样品,主要是通过SEM和XRD的方法对其来进行表征与分析。24840 毕业论文关键词:二氧化钛;水热法;光催化;甲基橙;降解
Research photocatalytic properties of titanium dioxide
Abstract: This article focused on the Preparation and photocatalytic properties of titanium dioxide prepared by hydrothermal synthesis of titanium dioxide, hydrochloric acid and titanium tetrachloride by ionic liquids and N-ethyl-pyridine tetrafluoroborate ([EPy] BF4) Synthesis of TiO2 powder. The nanometer particles TiO2 could be analyzed and characterized by XRD spectra and SEM.The photocatalytic activity of TiO2 could be studied through the degradation of methyl orange. Experimental studies have shown that the higher the surface area, the more active groups, the higher the photocatalytic activity for the adsorption of methyl orange the more obvious.
Key Words: TiO2; Hydrothermal method; photocatalysis; methyl orange; degradation
