Two-dimensional (2D) carbon nanomaterials generally display some limitations in adsorption applications due to easy agglomeration. To solve this problem, as-synthesized sandwiched nanocomposites made of Fe3O4 nanoparticles, poly(allylamine) hydrochloride molecules, and carboxylate graphene oxide sheets were prepared using a layer-by-layer (LbL) self-assembly method. The successfully synthesized sandwiched structures in the present nanocomposites have outstanding organic dye adsorption performance, stability, and recycling. The agglomeration of carboxylate graphene oxide was reduced with increased specific surface area because the Fe3O4 nanoparticles play important roles in interpenetrating and supporting graphene oxide sheets layers. In comparison with other kinds of composite adsorbents, the preparation process of the present new sandwiched composite materials is facile to operate and regulate, which demonstrates potential large-scale applications in wastewater treatment and dye removal.

层状组装构造的三明治式Fe 3 O 4 /羧酸氧化石墨烯纳米结构,用于高效高效和可磁回收的染料去除

二维(2D)碳纳米材料由于易于团聚,因此在吸附应用中通常显示出一些限制。为了解决该问题,使用层-层(LbL)自组装方法制备了由Fe 3 O 4纳米颗粒,聚(烯丙胺)盐酸盐分子和羧酸根氧化石墨烯片制成的合成的夹心纳米复合材料。在本纳米复合材料中成功合成的夹心结构具有出色的有机染料吸附性能,稳定性和可回收性。随着Fe 3 O 4的增加,羧酸盐氧化石墨烯的团聚随着表面积的增加而降低。纳米颗粒在互穿和支撑氧化石墨烯片层中起重要作用。与其他类型的复合吸附剂相比,本发明的新型夹层复合材料的制备工艺易于操作和调节,证明了其在废水处理和染料去除中的潜在大规模应用。
