概述

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(TiO 2 )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

Titanium dioxide (TiO 2 , titania) is one of the most important materials having various important applications, such as water and air purification, self-cleaning materials and photovoltaic cells. TiO 2 is an n-type semiconductor having a wide band gap (3.2eV for anatase and 3.0eV for rutile). Deposition of thin films of TiO 2 doped with Mn on F-doped SnO2-coated glass by spin coating has been described. Deposition of thin films of titanium dioxide (TiO 2 ) on various substrates by a simple sol-gel dip coating technique has been proposed. It has various photocatalytic applications where it can be used in two forms, i.e as highly dispersed fine particles on porous support materials and as suspended fluids in liquid medium. Titanium(IV) oxide is a white colored compound, which can be used as a coloring pigment in paints and a main ingredient of cosmetics and toothpaste. It can be prepared via reaction of titanium(IV) chloride with oxygen gas. It can also find applications in photovoltaics, photocatalysis and gas sensors.
