Abstract: Eco-friendly and cost-effective synthesis of TiO2 nanoparticles for efficient heavy metal removal from wastewater and high effective solar cell development. This The proposed project investigates the possibility of eco-friendly synthesis of titanium dioxide Ti02 nanoparticles using dry plant extracts of neem leaves, jasmine flowers, green tea leaves, as well as basil leaves. The phytochemicals present in these botanicals include polyphenols, flavonoids, alkaloids, and terpenoids which are natural biomolecules that perform reducing and stabilizing functions during the formation of the nanoparticle, and lead to bio-synthesized TiO2 nanoparticles with improved surface properties, stability, and functionality because of the capping effects of these phytochemicals. The green synthesis method is a non-toxic, costeffective, and sustainable method of making nanoparticles in comparison to the traditional physical and chemical processes^that use dangerous chemicals and conditions that use energy. These bio-synthesized TiO2 nanoparticles have a significant potential in environmental remediation particularly in adsorption and removal of cadmium ions- a dangerous heavy metal pollutant- in industrial wastewater. TiO2 nanoparticles have a high surface area and adsorptive capacity, and thus, they effectively trap cadmium, which decreases related health and environmental hazards. Moreover, the salvaged cadmium may be recycled and converted into useful cadmium-based finishes, like cadmium sulphide (CdS) or cadmium telluride (CdTe), which are used in the production of solar photovoltaic cells, and produces a closedloop solution bridging waste management and renewable energy technology. This interdisciplinary project is sustainable in that it can show a cycle of making functional nanomaterials using natural sources, using them to clean the environment and using recovered pollutants as renewable energy resources. This strategy is not only a step towards environmental protection, but also an innovative solution to waste valorisation and sustainable energy production
