“…However, the trace amount of fullerenes can be used to fabricate other materials like activated carbon, lignin, and zeolites to increase their efficiency of adsorption [63]. The fabrication of fullerene increases the hydrophobic character that makes materials better to be applied in adsorption and also helps in easier recycling [64]. Antibacterial material has been reported to be formed by grafting fullerene C 60 with polyvinylpyrrolidone (PVP) which has the potential to be applied in water disinfection.…”

Nanotechnology is an advanced field of science having the ability to solve the variety of environmental challenges by controlling the size and shape of the materials at a nanoscale. Carbon nanomaterials are unique because of their nontoxic nature, high surface area, easier biodegradation, and particularly useful environmental remediation. Heavy metal contamination in water is a major problem and poses a great risk to human health. Carbon nanomaterials are getting more and more attention due to their superior physicochemical properties that can be exploited for advanced treatment of heavy metal-contaminated water. Carbon nanomaterials namely carbon nanotubes, fullerenes, graphene, graphene oxide, and activated carbon have great potential for removal of heavy metals from water because of their large surface area, nanoscale size, and availability of different functionalities and they are easier to be chemically modified and recycled. In this article, we have reviewed the recent advancements in the applications of these carbon nanomaterials in the treatment of heavy metal-contaminated water and have also highlighted their application in environmental remediation. Toxicological aspects of carbon-based nanomaterials have also been discussed.

“…Alekseeva et al reported that a C 60 -based nanocomposite-PS film which had better efficiency for the removal of Cu 2+ ions, following a Langmuir model [140]. The fabrication of C 60 -based polymer film increases its hydrophobicity, which makes them better in adsorption and easier in recycling [141]. Asymmetric UF membranes based on poly(phenylene isophtalamide)-C 60 composite membranes were prepared by a phase inversion technique [96].…”

With the rapid growth of industrialization, diverse pollutants produced as by-products are emitted to the air-water ecosystem, and toxic contamination of water is one of the most hazardous environmental issues. Various forms of carbon have been used for adsorption, electrochemical, and ion-exchange membrane filtration to separation processes for water treatment. The utilization of carbon materials has gained tremendous attention as they have exceptional properties such as chemical, mechanical, thermal, antibacterial activities, along with reinforcement capability and high thermal stability, that helps to maintain the ecological balance. Recently, engineered nano-carbon incorporated with polymer as a composite membrane has been spotlighted as a new and effective mode for water treatment. In particular, the properties of zero-dimensional (0D) carbon forms (fullerenes and carbon dots) have encouraged researchers to explore them in the field of wastewater treatment through membrane technologies as they are biocompatible, which is the ultimate requirement to ensure the safety of drinking water. Thus, the purpose of this review is to highlight and summarize current advances in the field of water purification/treatment using 0D carbon-polymer-based nanocomposite membranes. Particular emphasis is placed on the development of 0D carbon forms embedded into a variety of polymer membranes and their influence on the improved performance of the resulting membranes. Current challenges and opportunities for future research are discussed.

“…Large-scale use of fullerenes is limited due to the prohibitive cost of fullerenes, Open Journal of Applied Sciences therefore small amounts of fullerenes are doped into adsorbents such as activated carbons. Samonin et al [40] showed that doping up to 0.004% of fullerenes into activated carbon increased the adsorption capacity for Pb 2+ and Cu 2+ by up to 2.5 times more.…”

The provision and demand for safe water continues to be a major aspect for governments worldwide as the population continues to grow accompanied by an increase in anthropogenic activities that contaminate water bodies. The common contaminants are the negatively charged ions such as sulfates, positive ions like heavy metals and organic molecules like dyes and phenols. Although, various methods exist for purification of wastewater, the adsorption process is a low cost method that uses readily available adsorbents. Activated carbon, although costly for developing countries, is still the most efficient adsorbent for a variety of substances. However, low cost adsorbents derived from biowaste have being actively explored in water purification. Photocatalytic nanostructured adsorbents not only play a bifunctional role in adsorbing contaminants but also are able to decompose organic pollutants in water using sunlight. The engineering of naturally abundant clay in most developing countries offers an even inexpensive way to clean-up wastewater.
