氧化铈/碳纳米复合纤维膜的制备及吸附和催化性能

Preparation,Adsorption and Catalytic Properties of Cerium Oxide/Carbon Nanocomposite Fiber Membranes

碳纳米纤维材料目前应用越来越广泛,将金属氧化物修饰到碳纳米纤维材料上,可以防止金属氧化物纳米颗粒的团聚。选用聚丙烯腈以及N,N-二甲基甲酰胺作为原材料,利用静电纺丝-煅烧法制备了氧化铈/碳纳米复合纤维膜,研究了复合纤维膜对水中As^(3+)、As^(5+)的吸附率,并以亚甲基蓝溶液作为污染物,研究了其催化和氧化性能,为材料优化和性能提升奠定了基础。

Carbon nanofiber materials are currently more and more widely used.The modification of metal oxides to carbon nanofiber materials can prevent the agglomeration of metal oxide nano-particles.Polyacry⁃lonitrile and N,N-dimethylformamide were selected as raw materials,and cerium oxide/carbon nanocompos⁃ite fiber films were prepared by electrospinning-calcination method.The adsorption rate of composite fiber membranes to As^(3+)and As^(5+)was studied,and its catalytic property and oxidation property were studied with methylene blue solution as a pollutant,which laid the foundation for future research.
