Nanomaterials for environmental governance and their sustainability

Because of the unique photocatalytic ability of nanomaterials, extremely large surface area and excellent adsorption capacity, nanomaterials have shown good development prospects in the broad field of environmental governance. In this paper, the specific methods used by nanomaterials in water treatment, soil treatment and air treatment are described in detail. In particular, the treatment of pollution caused by heavy metals, oil and microorganisms caused by nanomaterials in water was discussed. As far as water treatment is concerned, nanomembranes prepared by electrospinning with ceramic metal oxides and mixed matrix materials have gradually evolved into the core means to deal with heavy metal pollution. In the process of petroleum treatment, the corresponding treatment is mainly carried out by means of a series of physical methods such as adsorbents, and in the process of microbial treatment, it is mainly achieved by relying on the active movement between ions. Finally, the paper also summarizes the possible impact of nanomaterials on the human body, which fully and effectively demonstrates the sustainability of nanomaterials in the practical application of environmental governance.
