Dear colleagues,

Carbon-based nanomaterials such as graphene, carbon nanotubes, carbon nanofibers, carbon quantum dots, carbon black, graphitic carbon nitride and many others play an important role in environmental analysis. They are widely used for environmental monitoring and pollution control because of their exclusive properties, such as larger surface area that can be easily modified with various functional groups, cost efficiency, environmental friendliness, high conductivity, and ability to form thin films. Due to the critical problem of the release of pesticides, antibiotics, and toxic heavy metals into the environment, there is an urgent need to develop exceptional materials to determine their presence in aquatic and terrestrial environments. The search for new composites and bio-nanocomposites that take an eco-friendly route to confirm efficient and environmentally friendly methods is an exciting way to remove or reduce environmental pollutants.

Currently, many researchers are focusing on carbon-based materials for the detection and removal of heavy metals, dyes, pesticides, nitroaromatic pollutants, inorganic anions, and phenolic compounds. Real-time monitoring of these important compounds that pose a risk to the environment requires an affordable material that is easy to manufacture and provides rapid results without compromising the sensitivity and accuracy.

This section collection is devoted to recent advances in the following topics:

· The synthesis strategies for various precursors used in the preparation and fabrication of carbon-based nanomaterials

· The use of carbon-based nanomaterials in the development of electrochemical sensors for environmental monitoring

· The application of carbon-based nanomaterials in remediation of hazardous substances and effective removal of pollutants

· The use of carbon-based nanomaterials as stabilizing and reducing agents for sustainable environmental control

All types of research approaches are acceptable. We invite and welcome all researchers to submit original research and review articles for this special issue of the journal.
