This research outlines the development, comprehensive analysis, and assessment of the photocatalytic and antibacterial properties of ZnO/ZnSnO₃ nanocomposite (NC). The nanocomposite was synthesized using an eco-friendly green synthesis method with lemon peel extract. Techniques such as XRD, SEM, and FTIR verified the formation of dual-phase ZnO/ZnSnO₃ NC with an energy gap of ~ 1.9 eV and an average crystallite size of ~ 25.45 ± 1.24 nm. Photocatalytic degradation evaluated for Evans Blue (EB) dye under solar light indicated high degradation efficiency ~ 99.57% during 90 min, following pseudo-first-order kinetics with a rate constant ~ 0.11 min⁻¹. Furthermore, ZnO/ZnSnO₃ NC exhibited notable antibacterial potential with inhibition zones ranging from (10.0 ± 1.3 to 12.0 ± 0.5) mm for E. coli and (9.0 ± 0.8 to 14.0 ± 0.6) mm for P. aeruginosa, with improved activity against K. pneumoniae and S. aureus. The as-prepared NC exhibited significant antifungal activity against C. albicans with inhibition zones ~ 22.0 ± 0.3 mm. The results obtained categorized ZnO/ZnSnO₃ NC as a potential candidate to be utilized for environmental cleanup and wastewater treatment. [ABSTRACT FROM AUTHOR] |
