标 题 :Synthesis of carbamate compounds
发明人：BERRIER JOHN VINCENT
权利人:ROHM & HAAS
摘要:Disclosed is a method for the preparation of carbamate compounds substantially free of by-products; the carbamate compounds being prepared by reacting an isocyanate with a hydroxylated compound in the presence of certain catalysts that increase the rate of carbamylation while decreasing the rate of by-product formation.

标题 :Electrochemical catalysts for fuel cells and methods of making and using the same
发明人：LI JUN; SEKAR ARCHANA
权利人:UNIV KANSAS STATE
摘要:Methods of making and using an improved electrochemical catalyst are provided herein. Catalysts as described herein include a carbon-containing support at least partially coated with a transition metal oxide shell. Catalytic nanoparticles, such as platinum nanoparticles, ruthenium nanoparticles, and/or PtRu alloy nanoparticles, are dispersed in and/or on the shell. The catalysts exhibit enhanced long-term stability and electrochemical activity, particularly with respect to the oxidation of methanol. Microwave-assisted synthesis and thermal annealing steps make the process of producing these catalysts both efficient and more easily scalable. The resulting catalysts have a wide range of end uses in renewable energy applications, including various types of fuel cells.

摘要:The invention relates to a high-throughput-method wherein mixed oxides are synthesised by means of a synthesis robot and tested by illuminous radiation for the suitability thereof for photocatalytical degradation of organic compounds. According to said inventive method, novel photocatalists are detected with visible light in light or water in order to reduce pollutants.

标题:Porous inorganic oxide materials prepared by non-ionic surfactant templating route
发明人：PINNAVAIA THOMAS J; BAGSHAW STEPHEN A
权利人:UNIV MICHIGAN STATE
摘要:A method for the preparation of new semi-crystalline, porous inorganic oxide compositions possessing uniform framework-confined mesopores in the range 2.0-10.0 nm. The method uses an interaction between various nonionic polyethylene oxide based surfactants (N DEG ) and neutral inorganic oxide precursors (I &squ& ) at ambient reaction temperatures. The materials formed exhibit a disordered assembly of worm-like channels of regular diameter owing to the specific mechanism of self-assembly, producing highly stable materials and particles incorporating large numbers of the channels. This (N DEG I DEG ) templating approach introduces several new concepts to mesostructure synthesis. The application of the low-cost, non-toxic and biodegradable surfactants and ambient reaction temperatures, introduces environmentally clean synthetic techniques to the formation of mesostructures. Recovery of the template can be achieved through solvent extraction where the solvent may be water or ethanol.

发明人：PINNAVAIA THOMAS J; PROUZET ERIC P
权利人:UNIV MICHIGAN STATE
摘要:A method for the preparation of new quasi-crystalline, porous inorganic oxide compositions formed in the presence of fluoride ion possessing a disordered assembly of worm-like channels. The method uses an interaction between various nonionic polyethylene oxide based surfactants (N DEG ) and neutral inorganic oxide precursors (I DEG ) in an aqueous solution and then the formation of dispersed particles in the aqueous solution in the presence of fluoride. This (N DEG I DEG F-) templating approach introduces several new concepts to mesostructure synthesis. The application of the low-cost, non-toxic and biodegradable surfactants and ambient reaction temperatures, introduces environmentally clean synthetic techniques to the formation of mesostructures. Recovery of the template can be achieved through solvent extraction where the solvent may be water or ethanol.
