Urgent remediation is needed to degrade the low-biodegradability dye molecules in dye-polluted water from textile industries, as this contamination has been recognized as a serious environmental issue, causing a range of harmful effects on both human health and ecosystems. In this milieu, the present study investigates the biofabrication of tin oxide nanoparticles (SnO2 NPs) using leaves extract from Morinda citrifolia and Pandanus amaryllifolius for the degradation of methylene blue (MB), benefaction an alternative solution to the issue of dye-polluted water. The synthesis method integrates tin chloride pentahydrate with the leaves extract, followed by calcination. Comprehensive characterization via FTIR, XRD, FESEM, EDX, HRTEM, and UV-Vis spectroscopy confirmed the successful formation of SnO2 NPs, revealing distinct morphological and crystalline properties. Photocatalytic tests demonstrated that SnO2 NPs derived from M. citrifolia achieved a superior degradation rate of 97%, compared to 80% from P. amaryllifolius, with optimal activity under neutral pH. While radical scavenger experiments identified electrons as the primary active species to accelerate the degradation and reusability tests indicated a gradual decline in efficiency over five cycles, demonstrating its stability. These findings underscore the superiority of biofabricated SnO2 NPs as a sustainable and efficient photocatalyst using these two plants, compared to other plant templates, in which pronounce promising avenues for environmental conservation and resource management.
