In this work. TiO2 photocatalysts were synthesized using a conventional sol-gel and hydrothermal synthesis methods with steam pressure treatment. Photocatalysts were characterized by X-ray diffraction (XRD). diffuse reflectance spectra (DRS) and N2 adsorption-desorption. https://www.ealisboa.com/great-deal-Pentair-Union-Collar-2-U11-200PS-super-offer/
