Ag负载TiO2纳米管的制备及其光催化性能的研究开题报告

摘要：

TiO2纳米管因具有高度结晶度和优异的光催化性能而备受关注。然而，TiO2纳米管在水中的稳定性有限。本研究将通过负载Ag的方法提高TiO2纳米管的稳定性和光催化性能。本文首先对TiO2纳米管制备方法进行介绍，包括水热法、模板法和气-液界面法等。然后介绍Ag负载TiO2纳米管的方法和影响因素，如Ag的浓度、沉积时间和温度等。最后研究Ag负载TiO2纳米管的光催化性能，主要通过降解染料和有机物来评估其催化效果，并探究其光催化机理。本研究有望提供一种有效的方法来提高TiO2纳米管的稳定性和光催化性能，进一步拓展其在环境污染治理和能源领域的应用。
