Environmental pollution and global warming are severe problems facing the world due to increased usage of fossil fuels and the size of the world's population. Thus, there is a need for smart materials with technological developments to overcome these problems. Therefore, we discuss the unique properties of various nanomaterials specially used for environmental remediation. The different types of nanomaterials discussed includes 0D nanoparticles, 1D nanorods, nanotubes, nanowires, and 2D nanosheet-based composite nanomaterials and nanostructures. It starts with a brief introduction followed by the various combinations of these nanomaterials viz., metal and non-metal doping, and composites of nanomaterials. Also discussed are the special properties of carbon-based nanomaterials like g-C3N4, carbon nanotubes, graphene, graphene oxide, and reduced graphene oxide. We explain how the special properties of these types of nanomaterials successfully address various critical environmental problems, such as organic dye degradation, air purification, and industrial waste water purification.

The removal of pollutants from wastewater and contaminated water is desired to prevent the pollution issues from becoming worse. In this context, polymer-based nanocomposites have been developed and emerged as one of the advanced materials that can be used to solve the environmental pollution challenges. This composite material is produced by combining nanomaterials with polymers and usually appears in the form of membranes, adsorbents, hydrogels, and aerogels. These polymer-based nanocomposites possess improved characteristics and properties compared to the original individual material. Subsequently, the pollutants removal capability of the polymer-based nanocomposites has been enhanced significantly, with some even attaining new functionalities such as antibacterial and photocatalytic.

To remove heavy metals from contaminated water, adsorption is one of the techniques that, due to its significant efficiency, low cost, simplicity, variety, selectivity for specific metals, less need to use chemical additives, and the possibility of regenerating and reusing the adsorbent, has been widely used. Although nano-adsorbents have considerable adsorption capacity, due to the nano scale of the particles their direct use in a discontinuous bed requires the integration of the adsorption process with an additional post-treatment process to completely remove the nanoparticles from the water before use. One of the suitable substrates to trap the nano-adsorbents are membrane structures called adsorbent membranes. This chapter deals with the synthesis, characterization, performance evaluation and challenges of adsorptive mixed matrix membranes for heavy metal removal.","PeriodicalId":443511,"journal":{"name":"Chemistry in the Environment","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115341631","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ever-increasing attention to applying a wide range of nanomaterials in functionalizing nanocomposites has led to incessant attempts to develop different functional nanocomposites with favorable properties. The present chapter addresses the prominent role of functional nanocomposites and their recent development for the remove of these pollutants.

Magnetic nanoparticles (MNPs) and nanocomposites have received significant attention over recent decades in both fundamental research as well as environmental sciences. The unique characteristics of these materials, such as high physical and chemical stabilities, biocompatibility, low toxicity, easy synthesis, excellent recycling capability, and processability under a magnetic field, make them promising candidates as part of the next-generation technology for the treatment of pollutants. Iron-based nanoparticles (INPs), including magnetite (Fe3O4), maghemite (γ-Fe2O3), hematite (α-Fe2O3), and goethite (α‐FeOOH) have been exploited in environmental applications such as the removal of metalloids, heavy metals, dyes, and organic compounds because of their large surface area to volume ratio, various morphologies, and catalytic properties. In fact, the large iron surface area plays an essential role in the interaction with pollutant contaminants. Unlike the bulk, MNPs exhibit unique magnetism, easily tuned to the desired applications. In this chapter, various properties, different synthesis methods, and characterization of magnetic NPs have been summarized. Finally, the application of the different MNPs have been considered to eliminate and purify hazardous and harmful pollutants from water and wastewater.","PeriodicalId":443511,"journal":{"name":"Chemistry in the Environment","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127510344","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
