摘要

在以铝合金为电极的电化学电池中，通过氧化石墨烯（GO）的电化学反应，制备了氧化石墨烯-氧化石墨烯纳米复合材料。将合成的纳米复合材料（B-GO）与聚砜（PS）和静电纺丝混合制备聚砜-薄铝石-氧化石墨烯微纤维，并用XRD和SEM对其进行了表征。该超细纤维在可见光（500瓦灯）和太阳能灯下用于检测其降解亚甲基蓝（MB, 100 ppm）的效率。研究了最佳条件（pH、投加量、时间、温度），结果表明，纳米纤维在可见光下对MB的降解率达80%以上，在太阳光下对MB的降解率达99%以上。

Removal of Methylene Blue by Degradation Using Polysulfone–Boehmite–Graphene Oxide Microfiber Photocatalyst Under Visible and Solar Lights

Boehmite–graphene oxide nanocomposite is prepared by electrochemical method via the reaction of graphene oxide (GO) within the electrochemical cell that contain aluminum alloy as electrodes. The resulted nanocomposite (B–GO) is mixed with polysulfone (PS) and electrospun to prepare polysulfone–boehmite–graphene oxide microfiber that is characterized by XRD and SEM. This microfiber is used to examine it efficiency in the degradation of methylene blue (MB, 100 ppm) under visible (500-W lamp) and solar lights. The optimal conditions (pH, dosage of B–GO, time, temperature) are studied, and the result show that the nanofibers are able to degrade more than 80% of MB under visible light and more than 99% under solar light.
