一般描述
二氧化钛 (TiO 2 ，titania) 是一种重要的材料，具有多种重要的应用，如水和空气净化、自清洁材料和光伏电池等。TiO 2 是一种具有宽禁带（锐钛矿为 3.2 eV，金红石为 3.0 eV）的 n 型半导体。采用旋涂法在 F 掺杂 SnO2 镀膜玻璃上制备了 Mn 掺杂 TiO 2 薄膜。本文提出了一种简单的溶胶-凝胶浸渍提拉法在不同的基片上沉积二氧化钛(TiO2)薄膜。它有多种光催化应用，可以两种形式使用，即高度分散在多孔载体材料上的细小颗粒和液体介质中的悬浮流体。
四氧化钛是一种白色化合物，可作为着色颜料 用于油漆中，也是化妆品和牙膏的主要成分。可通过氯化钛 (IV) 与氧气反应制备。它还可以在光伏、光催化和气体传感器中找到应用。
