Abstract
As the global population grows, the demand for cost-effective and eco-friendly water purification methods is increasing, which presently is at its peak due to the increase of impurities in water and the increasing awareness of waterborne disease. Carbon-based materials, which includes activated carbon, carbon nanotubes (CNTs), graphene, graphene oxide (GO), reduced graphene oxide (rGO), fullerene, and carbon dots, are observed as potential candidates for water treatment. In the present review, developments related to water purification methods using carbon nanomaterials over the last decade are critically summarized, with an emphasis on their thermophysical properties. The fabrication techniques for activated carbon, CNTs, graphene, and graphene oxide are presented, with an emphasis on the properties of carbon materials that allow their usage for water purification. Then, an extensive review of 71 patents dedicated to water purification using carbon materials such as activated carbon and cotton fibers is performed. Subsequently, the more important research studies on water purification using carbon nanomaterials are discussed, showing that CNTs, GO, and rGO are widely used in water treatment processes. The present review critically discusses the recent developments and provides important information on water purification using carbon materials.
Highlights
Water is the most abundant and irreplaceable resource available globally, despite its importance, water scarcity is occurring due to the rapid increase in the global population, intense industrialization, stringent water quality standards, and negative climate change [1]
In 2013, Dimiev et al [30] revisited the structure via acid titration and ion exchange experiments in terms of the acidity of Graphene oxide (GO) and proposed a novel dynamic structural model (DSM), which describes the evolution of several carbon structures with attached water molecules beyond the static

Summary
Water is the most abundant and irreplaceable resource available globally, despite its importance, water scarcity is occurring due to the rapid increase in the global population, intense industrialization, stringent water quality standards, and negative climate change [1]. It can be observed that activated carbon, CNTs, and graphene are the most used carbon materials This reflects the increase in attention from the research community towards testing carbon-based nanoparticles in water purification systems. The recent review on nanoparticles carbon-based for water purification provides insightsprovides on heavyinsights metal removal [35], metal osmosis membranes and nanoparticles for water purification on heavy removal [35], [36], osmosis carbon material [37]. The present review covers articles and patents related to water membranes [36],properties and carbon material properties.
