Ultrasound-assisted phyto-mediated synthesis of SnO2 nanoparticles as photocatalyst in tetracycline photocatalytic oxidation
Antibiotic-containing wastewater from pharmaceutical industries have become serious organic pollutants need to be serious treated, and one of the important antibiotics is tetracycline (TC). Advanced oxidation process (AOPs) including photocatalytic oxidation is recognized as efficient method. Respec...

Antibiotic-containing wastewater from pharmaceutical industries have become serious organic pollutants need to be serious treated, and one of the important antibiotics is tetracycline (TC). Advanced oxidation process (AOPs) including photocatalytic oxidation is recognized as efficient method. Respect to the emergence of nanomaterials utilization in many aspects, syntheses of nanoparticles and nanomaterials photocatalyst are also developed. With consideration of green chemistry approach, in this research, phyto-mediated synthesis of SnO2 nanoparticles (SnO2 NPs) by using Tinosphora cordifolia stem extract with the applied ultrasound irradiation method was conducted. Study on the effect of calcination temperature to the physicochemical feature and photocatalytic activity towards TC photooxidation were focused. The NPs samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), ultraviolet–visible diffuse reflectance spectra (UV–vis DRS), and x-ray photoelectron spectroscopy (XPS). The results showed a single phase SnO2 produced at two varied calcination temperature of 200 °C and 500 °C with the particle size ranging at 2–7 nm, and 5–15 nm, respectively.
