Morphological, structural and antibacterial behavior of eco-friendly of ZnO/TiO2 nanocomposite synthesized via Hibiscus rosa-sinensis extract

An eco-friendly preparation technique was used to synthesize zinc oxide (ZnO) from Hibiscus rosa-sinensis extract. In addition, titanium dioxide (TiO2) combined with ZnO in a nanocomposite. The structural investigation done by x-ray diffraction (XRD) and the hexagonal symmetry of detected. calculated crystallite size increased 31.3 34.4 nm. Furthermore, functional groups organic residues were detected chemical analysis Fourier transform infrared spectroscopy (FTIR). rod grains TiO2 scanning electron microscope (SEM). Further, length 0.87 4.5 ?m. Besides, width 0.27 2 ?m (from ZnO/TiO2 respectively). decreased 536 337 nm, while 136 122 A transmission (TEM) investigate particles composite. as ellipsoidal around 123 91 respectively. Besides sphere diameter 25 composites without harmful chemicals could be suggested for biological applications. inhibition zone values E. coli S. aureus microorganisms 61.4 ± 3.6 39.6 4.4 has been doping 82.3 6.7 54.3 2.8.
