Nano Green Chemistry for Sustainable Environmental Remediation: Recent Advances and Future Perspectives
Summary
Scientists are using natural ingredients like plant extracts, algae, and fungi to create tiny, eco-friendly particles (nanoparticles) that can clean up pollution more safely than traditional chemical methods. This review paper summarizes existing research showing these "green" nanomaterials can help remove harmful substances like heavy metals, pesticides, drug residues, microplastics, and disease-causing germs from water, soil, and air. This matters because it points toward cleanup technologies that reduce our exposure to contaminants without introducing new toxic chemicals into the environment in the process.
Environmental pollution resulting from rapid industrialization, urbanization, intensive agriculture, and unsustainable resource utilization has become a major global concern requiring innovative, efficient, and environmentally sustainable remediation technologies. Conventional treatment methods often involve high energy consumption, toxic chemicals, secondary waste generation, and limited pollutant removal efficiency. Nano green chemistry has emerged as an interdisciplinary field that combines the principles of green chemistry with nanotechnology to develop environmentally benign nanomaterials and sustainable remediation strategies. Green-synthesized nanoparticles, nanocomposites, bio-based nanomaterials, metal oxides, carbon nanomaterials, and nanocatalysts have demonstrated exceptional potential for removing heavy metals, dyes, pharmaceuticals, pesticides, emerging contaminants, microplastics, and pathogenic microorganisms from contaminated water, soil, and air. Plant extracts, microorganisms, algae, fungi, agricultural wastes, and natural polymers are increasingly utilized as eco-friendly reducing and stabilizing agents for nanoparticle synthesis, minimizing hazardous chemical usage while improving material biocompatibility. Recent advances in photocatalysis, adsorption, membrane technologies, advanced oxidation processes, environmental sensing, and multifunctional nanocomposites have further expanded the applications of nano green chemistry in environmental remediation. This review discusses the fundamental principles, green synthesis approaches, nanomaterial classifications, remediation mechanisms, recent environmental applications, current challenges, and future perspectives of nano green chemistry for sustainable environmental management
