Studies from Nanjing University Add New Findings in the Area of Hydrogen

June 3, 2014



By a News Reporter-Staff News Editor at Life Science Weekly -- Investigators publish new report on Hydrogen. According to news reporting from Jiangsu, People's Republic of China, by NewsRx journalists, research stated, "CuO/TiO2 composites were prepared by the impregnation method, in which TiO2 nanosheets and nanorods are used as the precursors, respectively. We investigated the effect of the TiO2 surface structure on the activity and recyclability of the photocatalysts."

The news correspondents obtained a quote from the research from Nanjing University, "The hydrogen production activities were tested in a 3molL(-1) methanol aqueous solution under UV-light irradiation. After deposition of Pt, both Pt@CuO/TiO2 samples displayed higher hydrogen production activities than the Pt/TiO2 samples. The results reveal that the TiO2 sheet-based samples display higher hydrogen production activities and stability than the TiO2 rod-based ones."

According to the news reporters, the research concluded: "It is proposed that a more stable p-n heterojunction form at the interface between CuO and TiO2 nanosheets owing to the strong interaction of CuO with the {001} facets of the TiO2 sheets, which significantly refrains the recombination rate of electrons and holes."
