Recent Findings in Chemical Engineering Described by Researchers from Sun Yat Sen University

June 18, 2014



By a News Reporter-Staff News Editor at Journal of Engineering -- Fresh data on Chemical Engineering are presented in a new report. According to news reporting out of Guangdong, People's Republic of China, by VerticalNews editors, research stated, "Highly ordered pore-through TiO2 nanotube arrays (TiNT) were prepared by an electrochemical anodization method and used as the support for a Pt/TiNT catalyst. The Pt/TiNT was then applied to the trace HCHO oxidation."

Our news journalists obtained a quote from the research from Sun Yat Sen University, "The effect of Pt/TiO2 structural properties on its performance was studied with respect to the behavior of adsorbed species on the catalyst surface using in situ DRIFTS. In comparison with the commercial TiO2 powders (P25 and anatase) supported Pt catalysts, Pt/TiNT shows higher activity under parallel preparation and test conditions. A HCHO conversion of 95% with a more than 100 h stable performance is achieved over Pt/TiNT at 30 degrees C with a low 0.4 wt % Pt loading amount. The superior performance is related to the specific monolith-like structure, confinement effect and metal-support interaction in Pt/TiNT."

According to the news editors, the research concluded: "Finally, the reaction mechanism is presented based on the in situ DRIFTS study and XPS characterization to explain the performance difference among the Pt/TiO2 samples with different morphologies."
