The aim of the present investigation is to synthesize β-MnO2 nanoparticles with the support of the extracts from the Chlorophytum borivilianum plant, an innovative and eco-friendly approach. Further, various characterization techniques including, UV–Vis spectroscopy, Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), transmission electron microscopy (TEM), and energy-dispersive X-ray spectroscopy (EDX), were performed to confirm the production, dispersion, morphology, and size of the prepared β-MnO2 nanoparticles. Here, the result of UV–Vis spectroscopy reveals the defined transitions of Mn4+ ions, and it also indicates a 3.21 eV bandgap value. The FTIR and EDX reports highlight the involvement of plant phytochemicals in the synthesis of β-MnO2 nanoparticles. Based on the structural characterization results of XRD and TEM, the nanoparticles are formed with tetragonal crystalline spherical morphology. The produced β-MnO2 nanoparticles have significant antibacterial performance against Shigella flexneri and also an outstanding activity in the degradation of methyl orange (MO) dye under visible light irradiation. The degradation kinetics exhibits a pseudo-first-order behavior, leading to the complete degradation of the hazardous dye, achieving 100% degradation efficiency. The synergistic effects of light absorption assisted by plant biomolecules, which promote catalytic activity and charge carrier recombination, are responsible for this extraordinary efficiency. The green-fabricated β-MnO2 nanoparticles show significant antibacterial capabilities and good catalytic performance against industrial dye pollution. This work establishes β-MnO2 nanoparticles as a viable option for upcoming wastewater treatment applications by highlighting the potential of sustainable synthesis techniques and biotechnological advancements in promoting environmental sustainability and tackling pollution issues.
