Direct fabrication of highly porous graphene/TiO2 composite nanofibers by electrospinning for photocatalytic application
【摘要】 本文报道了一种利用静电纺丝制备高度多孔的石墨烯/TiO2复合材料纳米纤维的方法。该方法通过静电纺丝将石墨烯与有机钛源复合,经450°C焙烧后得到分布均匀、具有高度多孔的石墨烯/TiO2复合材料纳米纤维。该复合材料表现出优异的光催化性能。制备石墨烯/TiO2复合材料纳米纤维的新方法用途广泛,可用于制备各种金属氧化物和石墨烯纳米复合材料。
【Abstract】 We reported the fabrication of highly porous graphene/TiO2 composite nanofibers in the form of a nonwoven mat by electrospinning followed by calcination in air at 450 °C. The graphene can uniformly disperse in highly porous TiO2 nanofibers. The highly porous graphene/TiO2 composite nanofibers exhibited excellent catalytic activities. The new method for producing graphene/TiO2 composite nanofibers is versatile and can be extended to fabricate various types of metal oxide and graphene nanocomposites.
