Nanoparticles for Environmental Remediation: - A green solution

Nanoparticles have been identified as a green approach to the treatment of pollutants and the improvement of the environment. The high surface area, reactivity, and the ability to introduce functional groups on the material make them suitable for the removal of impurities from water, soil, and air. This study discusses different categories of nanoparticles; metallic, carbonaceous, polymeric, and biogenic nanoparticles and their working principles like adsorption, photocatalytic reduction, and chemical reduction. Particular consideration is given to the green synthesis of nanoparticles, which employs plant and microbial extracts to reduce the toxicity and environmental effects of the process. However, there are some limitations such as cost, scalability, and toxicity which must be overcome in order to apply them. The objective of this work is to bring into focus the potential of nanoparticles in environmental remediation and the future research directions to overcome the existing challenges for developing more eco-friendly remediation technologies.
