摘要
以硝酸铁为原料,通过改变部分原料(N aOH,CH3COONa,H2O2)在无模版剂条件下水热法成功合成出纯相的短棒状、长棒状、颗粒状等形貌的A-FeOO H纳米晶体,并考察了其可见光光催化活性。结果表明:所获的A-F eO OH纳米晶体可用作F ento n催化剂,短棒状A-FeOO H在添加少量的N aF和H2O2条件下,光催化性能显著提高,罗丹明B降解率可由6.8%增加到93.6%。
α-FeOOH with different morphologies （short rod-like, long rod-like and irregular particles） was synthesized by template-free hydrothermal method using iron nitrate, NaOH, CH3COONa and H2O2 as the raw materials. Visible light induced photocatalytic degradation of rhodamine B on obtaineda-FeOOH nanocrystals was investigated. The results show that α-FeOOH can be used as Fenton catalyst and its degradation photoactivity of rhodamine B is significantly promoted by addition small amount of H2O2 and NaF. The degradation ration for rhodamine B sharply increased from 6.8% to 93.6% by synergistic effect of H2O2 and NaF.
