表面活性剂修饰碳酸氧铋的制备及光催化性能
Preparation and Photocatalytic Properties of Bismuth Subcarbonate Modified with Surfactants
摘要
Abstract
Bi2O2CO3 was synthesized by surfactant-assisted hydrothermal method.The dosage of cationic surfactant cetyltrimethylammonium bromide ( CTAB ) , nonionic surfactant polyethylene glycol 8000 (PEG8000), anionic surfactant sodium dodecyl sulfate(SDS), and coupling of SDS with CTAB as well as their influences on crystal plane, morphology, photoabsorption ability and photocatalytic activity of Bi2O2CO3 photocatalyst were investigated.The photocatalytic activity was evaluated by the degradation of rhodamine B solution(10 mg/L) under ultraviolet light irradiation.The results show that when the addition of Bi2O2 CO3 is 6 mmol(2.9106 g) , modified Bi2O2CO3 with SDS will inhibits the photocatalytic activity.The photocatalytic activity of Bi2O2CO3 is effectively improved by addition of 0.6 g CTAB in the hydrothermal process .A totally 0.3 g of SDS and CTAB can improve the photocatalytic activity of Bi2O2CO3 .Addition of 0.3 g PEG8000 also promotes the photocatalytic activity of Bi2O2CO3 .关键词
