The utilization of two-dimensional nanomaterials in environmental remediation offers significant advantages. These materials possess a high surface area, which allows for efficient adsorption andorption of pollutants, as well as the promotion of photocatalytic reactions. Their unique surface chemistry enables the modification of physicochemical properties, such as pH and surface charge, to enhance the efficiency of water treatment processes. Moreover, two-dimensional nanomaterials can be designed to have specific structures and porosities, which enable them to selectively capture and remove contaminants from water, such as heavy metals and organic pollutants.

In the field of adsorption, two-dimensional nanomaterials such as graphene and carbon nanotubes have shown promising results. These materials can adsorb a wide range of pollutants, including heavy metals, organic compounds, and dyes, from water and wastewater. Their high surface area and chemical properties enable them to selectively adsorb specific pollutants, while their porous structure allows for easy removal of adsorbed pollutants. Photocatalytic reactions, on the other hand, have been extensively studied using two-dimensional nanomaterials, such as titanium dioxide and zinc oxide. These materials can degrade organic pollutants, such as pesticides and industrial waste, into harmless byproducts through the absorption of sunlight and the activation of catalysts.

Membrane separation is another area where two-dimensional nanomaterials have shown great potential. These materials can be used to create highly selective membranes that can separate different components of water or wastewater. For example, graphene oxide membranes have been developed to selectively filter out bacteria and viruses from water, while carbon nanotube membranes have been used to separate organic compounds from water.

Desalination is another critical application where two-dimensional nanomaterials have shown promise. These materials can be used to create efficient desalination systems that can produce clean water from saltwater. For example, graphene oxide membranes have been used to enhance the efficiency of reverse osmosis desalination systems, while carbon nanotube membranes have been used to improve the performance of thermal desalination systems.

Deionization is another application where two-dimensional nanomaterials have shown potential. These materials can be used to create efficient deionization systems that can remove ions from water, such as chloride and sodium. For example, graphene oxide membranes have been used to create deionization systems that can produce high-quality water for drinking and other applications.

Environmental pollutants sensing/detection is another area where two-dimensional nanomaterials have shown great promise. These materials can be used to create sensitive and selective sensors that can detect the presence of pollutants in water or air. For example, graphene oxide sensors have been developed to detect the presence of heavy metals and organic pollutants in water, while carbon nanotube sensors have been used to detect the presence of volatile organic compounds in air.

Carbon-dioxide capture and catalytic conversion is another critical application where two-dimensional nanomaterials have shown potential. These materials can be used to create efficient carbon capture and conversion systems that can reduce the amount of carbon dioxide in the atmosphere. For example, graphene oxide membranes have been used to create carbon capture systems that can capture carbon dioxide from flue gases, while carbon nanotube membranes have been used to create catalytic converters that can convert carbon dioxide into methane.

Microbial treatment is another area where two-dimensional nanomaterials have shown potential. These materials can be used to create effective antimicrobial agents that can kill bacteria and viruses in water or wastewater. For example, graphene oxide membranes have been used to create antimicrobial agents that can kill bacteria and viruses in water, while carbon nanotube membranes have been used to create antimicrobial agents that can kill bacteria and viruses in wastewater.

Electrochemical remediation is another application where two-dimensional nanomaterials have shown potential. These materials can be used to create effective electrochemical remediation systems that can remove pollutants from soil or water. For example, graphene oxide electrodes have been used to create electrochemical remediation systems that can remove heavy metals from soil, while carbon nanotube electrodes have been used to create electrochemical remediation systems that can remove organic pollutants from water.

In conclusion, two-dimensional nanomaterials have emerged as a promising solution for environmental applications due to their remarkable properties, including high surface area and tunable surface chemistry. This book presents a comprehensive compilation of contributed chapters from renowned international researchers who are at the forefront of developing state-of-the-art two-dimensional nanomaterials for various environmental applications. The utilization of two-dimensional nanomaterials in environmental remediation offers significant advantages, including efficient adsorption andorption of pollutants, promotion of photocatalytic reactions, selective capture and removal of contaminants, membrane separation, desalination, deionization, environmental pollutants sensing/detection, carbon-dioxide capture and catalytic conversion, microbial treatment, and electrochemical remediation. As the field of two-dimensional nanomaterials continues to evolve, it is expected to play an increasingly important role in promoting environmental sustainability and addressing the challenges posed by environmental pollution.
