Findings on Photocatalytics Detailed by Investigators at Institute of Urban Environment

June 27, 2014

By a News Reporter-Staff News Editor at Science Letter -- Investigators publish new report on Photocatalytics. According to news reporting from Xiamen, People's Republic of China, by NewsRx journalists, research stated, "Anatase TiO2 with exposed {001} facets has been deepgoingly studied for optimizing its photocatalytic activity. In this study, we synthesized N-doped TiO2 nanocrystals with exposed {001} facets by sol-gel method and solvothermal method, respectively."

The news correspondents obtained a quote from the research from the Institute of Urban Environment, "The physical and chemical properties of as-synthesized samples, such as morphology, crystal phase, surface elements composition, porous structure, specific surface area, and optical response, were characterized in detail. The photocatalytic performances of all samples were evaluated by photocatalytic decoloration of methylene blue under visible-light irradiation (lambda > 420 nm)."

According to the news reporters, the research concluded: "The results showed that the as-prepared samples present high visible-light photocatalytic performances, which can be ascribed to the excellent crystallization, the enhancement of absorbance in the visible-light region, and the strong adsorption performance, and calcination treatment is helpful to further improve the visible-light photocatalytic performance of N-doped TiO2 nanocrystals with exposed {001} facets."
