The graphene-based film is an interlayer separation film having a special mass transfer property. In this study, a novel TiO₂ nanorod inserted graphene-based membrane on a CA (Cellulose Acetate) mat was fabricated by a vacuum filtration method for water treatment application. The intercalated TiO₂ nanorods expanded the interlamellar spacing among the graphene sheets and thus advanced the separation efficiency of graphene-based membrane, which exhibited a flux several times higher than some commercial nanofiltration membranes and an extremely high rejection especially for dyes, for MB (99.3%), Rhb (99.4%), MO (99.3%), CR (99.6%).

新型光催化自清洁TiO ₂纳米棒插入氧化石墨烯基纳米过滤膜

石墨烯系膜是具有特殊的传质性的层间隔离膜。在这项研究中，一种新颖的TiO ₂纳米棒插入在石墨烯（纤维素醋酸酯）垫上的石墨烯基膜通过真空过滤方法进行水处理应用。插层的TiO ₂纳米棒扩大了石墨烯片之间的层间间距，从而提高了石墨烯基膜的分离效率，该膜的通量是某些商用纳滤膜的几倍，对甲基溴的截留率极高，尤其是对于染料而言（99.3 ％），Rbb（99.4％），MO（99.3％），CR（99.6％）。
