Here we overview the recent advances in the fabrication of sustainable composite nanomaterials with decontamination capacity towards inorganic and organic pollutants. In this regards, we present the development of hybrid systems based on clay nanoparticles with different shapes (such as kaolinite nanosheets and halloysite nanotubes) and organic molecules (biopolymers, surfactants, cucurbituril) as efficient removal agents for both aliphatic and aromatic hydrocarbons. Due to their high specific surface area, clay nanoparticles have been successfully employed as fillers for composite membranes with excellent filtration capacity. The preparation of composite gel beads based on biopolymers (alginate and pectin) and halloysite nanotubes has been discussed and their adsorption capacities towards both heavy metals and organic dyes have been highlighted. We describe the successful preparation of kaolinite/graphene composites as well as tubular inorganic micelles obtained by the select functionalization of the halloysite cavity with anionic surfactants. Finally, recent research on Pickering emulsions (for oil spill remediation) and bioremediation technologies has been discussed.
在此，我们概述了具有对无机和有机污染物去污能力的可持续复合纳米材料制备方面的最新进展。在这方面，我们介绍了基于不同形状的粘土纳米颗粒（如高岭土纳米片和埃洛石纳米管）以及有机分子（生物聚合物、表面活性剂、葫芦脲）的混合体系的开发，这些体系可作为脂肪族和芳香族烃的高效去除剂。由于其高比表面积，粘土纳米颗粒已成功用作具有出色过滤能力的复合膜的填料。讨论了基于生物聚合物（海藻酸盐和果胶）和埃洛石纳米管的复合凝胶珠的制备，并强调了它们对重金属和有机染料的吸附能力。我们描述了高岭土/石墨烯复合材料以及通过用阴离子表面活性剂对埃洛石空腔进行选择性功能化获得的管状无机胶束的成功制备。最后，讨论了关于皮克林乳液（用于溢油修复）和生物修复技术的最新研究。
