By a News Reporter-Staff News Editor at Science Letter -- Fresh data on Photocatalytics are presented in a new report. According to news reporting originating from Alicante, Spain, by NewsRx correspondents, research stated, "Titanium dioxide nanoparticles prepared in situ by sol-gel method were supported on a spherical activated carbon to prepare TiO2/AC hybrid photocatalysts for the oxidation of gaseous organic compounds. Additionally, a granular activated carbon was studied for comparison purposes."
Our news editors obtained a quote from the research from the University of Alicante, "In both types of TiO2/AC composites the effect of different variables (i.e., the thermal treatment conditions used during the preparation of these materials) and the UV-light wavelength used during photocatalytic oxidation were analyzed. The prepared materials were deeply characterized (by gas adsorption, TGA, XRD, SEM and photocatalytic propene oxidation). The obtained results show that the carbon support has an important effect on the properties of the deposited TiO2 and, therefore, on the photocatalytic activity of the resulting TiO2/AC composites. Thus, the hybrid materials prepared over the spherical activated carbon show better results than those prepared over the granular one; a good TiO2 coverage with a high crystallinity of the deposited titanium dioxide, which just needs an air oxidation treatment at low-moderate temperature (350-375 degrees C) to present high photoactivity, without the need of additional inert atmosphere treatments."
According to the news editors, the research concluded: "Additionally, these materials are more active at 365 nm than at 257.7 nm UV radiation, opening the possibility of using solar light for this application."
