表面活性剂修饰碳酸氧铋的制备及光催化性能
|
摘要
采用水热法,以阳离子表面活性剂十六烷基三甲基溴化铵(CTAB)、非离子型表面活性剂聚乙二醇8000(PEG8000)、阴离子表面活性剂十二烷基硫酸钠(SDS)及SDS与CTAB耦合修饰Bi_2O_2CO_3。系统地研究了表面活性剂种类及用量对Bi_2O_2CO_3晶面、形貌、光吸收特性及光催化降解效率的影响。以紫外光下降解罗丹明B(Rh B),考察样品的光催化性能。结果表明,当Bi盐投加量为6 mmol(2.9106 g)时,SDS对Bi_2O_2CO_3的修饰对其光催化活性有所抑制;0.6 g CTAB修饰Bi_2O_2CO_3能有效提高其光催化活性;0.3 g SDS与CTAB耦合修饰Bi_2O_2CO_3就能有效提高其光催化活性;0.3 g PEG8000修饰Bi_2O_2CO_3也能使其光催化活性有所提高。
Bi_2O_2CO_3 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 Bi_2O_2CO_3 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 Bi_2O_2CO_3 is6 mmol( 2. 9106 g),modified Bi_2O_2CO_3 with SDS will inhibits the photocatalytic activity. The photocatalytic activity of Bi_2O_2CO_3 is effectively improved by addition of 0. 6 g CTAB in the hydrothermal process. A totally0. 3 g of SDS and CTAB can improve the photocatalytic activity of Bi_2O_2CO_3. Addition of 0. 3 g PEG8000 also promotes the photocatalytic activity of Bi_2O_2CO_3.
