Abstract
Strontium oxide (SrO) nanoparticle and various concentrations of chitosan (CS)-doped SrO nanocomposite were synthesized via co-precipitation method. A variety of characterization techniques including were done for characterizing and qualifying the nanocomposite. X-ray powder diffraction affirmed cubic and tetragonal structure of SrO nanoparticle and CS-doped SrO nanocomposite with a decrease in crystallinity upon doping. Fourier transform infrared spectrum endorsed existing functional groups on CS/SrO surfaces while d-spacing was estimated using high resolution Transmission electron microscopes images. UV-Visible and Photoluminescence spectroscopy spectra showed an increase in band gap energies with an increase in doping concentration. Elemental composition of CS-doped SrO nanocomposite deposited with different doping concentrations was studied using Energy dispersive Spectroscopy. Addition of chitosan resulted in the formation of nanocomposite and rod-like structures that led to enhanced catalytic activity during methylene blue ciprofloxacin degradation in the presence of reducing agent sodium borohydrate at various pH conditions.
