Green fabrication of silver imprinted titania / silica nanospheres as robust visible light-induced photocatalytic wastewater purification

Herein, the Inexpensive Phyto-synthetic approach using green tea extract to fabricate silver greenly imprinted TiO2 nanoparticles modified mesoporous silica nanocomposite (Ag/TNPs-MSNs) is reported. The nano- composites were featured by using UV–vis diffuse reflectance spectra, X-ray Diffraction (XRD), X-ray Photo- electron Spectroscopy (XPS), nitrogen Sorption, High-resolution transmittance electron microscopy (HRTEM) and Field Emission Scanning Electron Microscopy (FESEM). Ag/TNPs-MSN bandgap evaluations are 2.78 eV compared to 3.16eV for TNPs-MSNs with ideal visible light capture capability, indicating the outstanding photodegradation activity of the synthesized nanocomposite. In addition, Ag/TNPs-MSNs photocatalytic effec- tiveness is evaluated in the degradation of aqueous solutions enriched with methylene blue (MB). The composite materials are extremely appropriate based on stability, recyclability/reusability, and a proper approach for visible-light-degradation of MB from the contaminated waters.
