Fe(Ⅲ)对纳米TiO_2光化学活性影响研究

Study on the effect of Fe(Ⅲ) on the photochemical activity of nanometer TiO_2

通过纳米ＴｉＯ２ 进行铁掺杂和以ＮａＡｃ 和ＮａＯＨ 处理得到的水合氧化铁包膜，来研究其光化学活性。结果表明，适当用量Ｆｅ（Ⅲ）能够增强它的光化学活性，而水合氧化铁包膜却能够降低其光化学活性。

The photochemical activity of Fe(Ⅲ) doped and hydrated ferric oxide coated (prepared by using NaAc and NaOH) nanometer TiO 2 is investigated. Experimental results show that the photochemical activity of nanometer TiO 2 can be enhanced by doping with a suitable amount of Fe(Ⅲ) and reduced by coating with hydrated ferric oxide.
