Environmental chemistry has seen a transformation thanks to quantum dots (QDs) because of their nanoscale dimension and adjustable fluorescent properties and their active surface chemistry. The combination of carbon and graphene quantum dots deliver photostable performance and low toxicity characteristics which enable their application in sensing pollutants and catalytic degradation systems and green energy devices. Scientists have proven recent breakthroughs in using heavy metal detection along with organic pollutant identification and pH and oxidative stress indicator analysis through fluorescence quenching and Förster resonance energy transfer mechanisms. The remediation field heavily benefits from QD applications because these nanoparticles excel at dye and endocrine disruptor photocatalysis and membrane systems for wastewater purification using adsorption and catalysis. Bio-derived and microwave-assisted and solvent-free synthesis approaches produce sustainable QD production methods while simultaneously improving QD tolerance to biological systems. The applications of QDs extend to renewable energy through their utilization in solar cell technologies and waste elimination systems. The continued use of quantum dots faces important obstacles because of their potential toxicity and environmental stability issues alongside the absence of specific regulatory systems. The complete sustainable utilization of QD technology requires both IoT and AI integration for real-time environmental tracking and multi-disciplinary collaborations and environmentally friendly policy development. The review integrates new findings about future deployment routes for QDs while explaining their potential environmental-scale sustainable implementation.
