Study Results from China University of Mining and Technology Provide New Insights into Photocatalytics [Characterizations of nano-TiO2/diatomite composites and their photocatalytic reduction of aqueous Cr (VI)]

By a News Reporter-Staff News Editor at Science Letter -- Investigators publish new report on Photocatalytics. According to news originating from Beijing, People's Republic of China, by NewsRx correspondents, research stated, "In this paper, the TiO2 nanoparticles were immobilized on diatomite (DIA) via a typical hydrolysis precipitation process using TiCl4 as precursor. The as-prepared composites were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS)."

Our news journalists obtained a quote from the research from the China University of Mining and Technology, "TiO2 nanoparticles with the average grain size of around 7-14 nm were well deposited on the surface of diatomite. The photocatalytic activity toward the reduction of aqueous Cr (VI) was demonstrated under UV light. The influence of initial pH values, catalyst amount, illumination intensity and initial concentration of Cr (VI) on photocatalytic reduction of Cr (VI) were investigated. Compared with the commercial TiO2 (P25, Degussa), the TiO2/DIA composites had better reactive activity because of their relatively higher adsorption capacity."

According to the news editors, the research concluded: "Furthermore, the prepared photocatalyst exhibited relatively good photocatalytic stability depending on the reusability tests."
