The development of plant-based photocatalyst with a minimum time of irradiation for water-soluble dye disposal from industries is a great significance to unravel water pollution. In the present work, the sol-gel synthesis method was employed for the synthesis of zinc oxide nanoparticles using Pluronic F127 and Aloe vera as dispersing media. A hexagonal wurtzite structure and surface morphology confirmed by XRD and FE-SEM analysis. The infrared study was applied to substantiate the acceptable compounds within the nanoparticles and phytochemicals presence within the extract. From the DRS spectra, Bandgap energy of ZnO nanoparticles (3.22eV) was decreased to 2.89eV by blending of Aloe vera and Pluronic F127 into ZnO. The photocatalytic action of different combinations of ZnO was examined against malachite green dye under UV light and visible light irradiation. Upto 95% degradation was achieved for ZnO/Aloe/PF127 with a minimum time of UV light exposure. All combinations of ZnO showed effective bactericidal activity against multi-drug resistance of E.coli, S.aureus, B.subtilis, and P.aeruginosa. These findings proved the overwhelming photocatalytic and antibacterial activity of ZnO samples, which might be used as effective remediation to treat textile dye wastewater.
