Carbonaceous Nanomaterials for Environmental Applications
Description
Over the last decade, novel synthesis methods for nanomaterials have been an interesting area in nanoscience and technology. However, the majority of the physical and chemical methods for the synthesis of nanomaterials have some limitations, such as being toxic to the health and environment, poor stability, a lack of fundamental mechanisms, easy agglomeration, the requirement of expensive chemicals, poor aqueous solubility, and needing a trained person to operate the synthesis instrument. Nowadays, the ‘green synthesis’ method has received a lot of attention, because of its easy synthesis, non-toxic raw materials, renewable resources, etc. Yet, algae, plants, bacteria, fungus, and viruses have been utilized for decades to create energy-efficient, sustainable, and eco-friendly nanomaterials synthesis. Among the different nanomaterials, carbonaceous nanomaterials, which include graphene oxide, carbon quantum dots, and carbon nanotubes, have been modified extensively with biogenic materials. The green synthesized carbonaceous nanomaterials exhibit outstanding physical, chemical, and mechanical properties and can be applied across fields.
It is well known that our global environment is being polluted by several toxins. Among them, water pollution is a major global environmental problem; polluted water should not be used for drinking purposes without purification. The main classes of pollutants are heavy metal ions and dyes. Green synthesized carbonaceous nanomaterials are now widely used for toxin sensors and environmental purification applications.
This Special Issue will focus on the synthesis and characterization of green synthesized carbonaceous nanomaterials and their environmental applications. The Special Issue will highlight chronic environmental issues that may be addressed through the use of carbonaceous nanomaterials. We encourage research related to toxic chemical removal from industrial polluted water, catalysts for organic processes to create important organic materials, homo and heterogeneous photocatalysis for environmental remediation, volatile organic compounds, and chemical sensors. We welcome both original research and review articles that highlight successes and advancements to date whilst also providing a future direction for developments in carbonaceous nanomaterials for a clean environment.
