Study Data from University of Bremen Update Understanding of Chemical Engineering (Generation of Pt- and Pt/Zn-containing ceramers and their structuring as macro/microporous foams)

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 Bremen, Germany, by VerticalNews editors, research stated, "In this work, a simple method is presented to generate hierarchically structured monolithic types of foam with high specific surface areas and good catalytic activities in a one-step process. The materials prepared are platinum- and zinc/platinum-containing hybrid ceramics generated by the pyrolytic conversion of a mixture of a methyl phenyl polysiloxane, 3-aminopropyltriethoxysilane, platininc acid or platinic acid, and a zinc salt."

Our news journalists obtained a quote from the research from the University of Bremen, "Foam structures are prepared by using a modified azodicarbonamide as the blowing agent and investigated in comparison to granulated samples. The low pyrolysis temperatures of 500 C and 600 C lead to porous materials with specific surface areas of 300-560 m(2) g(-1) due to microporosity, so that in the case of the foam structures, hierarchically ordered macro/microporous materials are generated."

According to the news editors, the research concluded: "Furthermore, it can be shown that the platinum is present as nanoparticles and the surface characteristic and catalytic activity in CO oxidation experiments are strongly dependent on the pyrolysis temperature and the presence of zinc."
