Properties, assembly and characterization of carbon nanotubes: their application in water purification, environmental pollution control and biomedicines—a comprehensive review

Owing to their simplicity and ease of synthesis, carbon nanotubes (CNTs) have captivated attention of researchers. Many engineering applications have investigated the new features of nanostructured carbon nanotubes, such as large surface area, stiffness and durability. CNTs have opened up new opportunities for environmental improvement, pollution management and application in a variety of fields. Multiple types of pollution are produced as a result of population growth, urbanization and industrialization. CNTs are used to solve a variety of challenges, including environmental difficulties, water pollution, biomedical applications, and so on. It becomes an unavoidable present and future material. Different applications of CNTs have been presented in this review paper. CNTs are potential material having number of uses, including water purification, drug delivery, preservatives, catalysis, genetic engineering and artificial implants which are reviewed in this review article. This paper is presenting an explicit and systematic progress of CNTs for water treatment, medicinal uses drug delivery, artificial implants and so on, and a multitude of CNT applications in broad disciplines and their purification methods have been covered. The issues related to synthesis technologies, purification technology, bio-medicinal application and catalytic property of CNTs within the framework of different engineering applications and environmental impact are discussed in this study. Graphical abstract The modified CNTs synthesis methods, structure, catalytic property, as preservatives, water purification technology and genetic engineering applications are all summarized in this paper. Due to their outstanding water purification property, high stability, high surface area and electroluminescent properties, these tubes are highly applicable in multiple fields; this review also discusses these tubes as a useful material in water purification, as a catalyst, and as a drug delivery agent.
