ABSTRACT
According to recent studies, approximately, four billion people (attributing to two-thirds of the world population) are presently facing severe water scarcity for at least a month every year. Contamination of water by different emerging pollutants is considered as one of the most reasons for global water scarcity. Due to an increasing global scarcity of potable water sources, laws regarding uses of water resources have become more stringent making it imperative to design new, efficient, cost-effective and time-saving 20methodologies for the treatment and reuse of wastewater. In recent studies, nanotechnology has received significant importance and a wide range of nanomaterials have been investigated for wastewater treatment. The present study reviews different graphene oxide (GO)–carbon nanotube (CNT)-based nanocomposites for their wastewater treatment potential. Special emphasis has been laid upon the mode of application, efficiency of pollutant removal, and antibacterial activity demonstrated by these novel nanocomposites. It also discusses the limitations as well as future challenges of using these nanocomposites for wastewater treatment. The different aspects of these nanocomposite-based water treatment discussed in this study will facilitate the potential readers including academicians, environmentalists, and industrialists trying to address issues of water scarcity.
