Publication number: 20110275842Abstract: Catalyst pellets with a high BET surface area can be formed from the compression of a submicron powder into the selected pellet shape, such as using a press that forms the pellet in a die. Catalysts of particular interest comprise a ceramic material with an elemental metal coating. A low temperature plasma treatment can be used to achieve desired surface modification. Catalysts are described that have high selectivities in ethylene epoxidation reactions run over long time periods. The improved catalysts are based upon catalyst materials, such as ytrria coated with silver, with high selectivities. High BET surface areas can be achieved by using a particulate ceramic support material.Type: ApplicationFiled: May 9, 2011Publication date: November 10, 2011Inventor: Gar B. Hoflund

Publication number: 20110269619Abstract: A soft-landing (SL) instrument for depositing ions onto substrates using a laser ablation source is described herein. The instrument of the instant invention is designed with a custom drift tube and a split-ring ion optic for the isolation of selected ions. The drift tube allows for the separation and thermalization of ions formed after laser ablation through collisions with an inert bath gas that allow the ions to be landed at energies below 1 eV onto substrates. The split-ring ion optic is capable of directing ions toward the detector or a landing substrate for selected components. The inventors further performed atomic force microscopy (AFM) and drift tube measurements to characterize the performance characteristics of the instrument.Type: ApplicationFiled: April 19, 2011Publication date: November 3, 2011Applicant: University of North TexasInventors: Guido Fridolin Verbeck, Stephen Davila

Publication number: 20110256469Abstract: A superior, industrially scalable one-pot ethylene glycol-based wet chemistry method to prepare platinum-adlayered ruthenium nanoparticles has been developed that offers an exquisite control of the platinum packing density of the adlayers and effectively prevents sintering of the nanoparticles during the deposition process. The wet chemistry based method for the controlled deposition of submonolayer platinum is advantageous in terms of processing and maximizing the use of platinum and can, in principle, be scaled up straightforwardly to an industrial level. The reactivity of the Pt(31)-Ru sample was about 150% higher than that of the industrial benchmark PtRu (1:1) alloy sample but with 3.5 times less platinum loading. Using the Pt(31)-Ru nanoparticles would lower the electrode material cost compared to using the industrial benchmark alloy nanoparticles for direct methanol fuel cell applications.Type: ApplicationFiled: April 7, 2011Publication date: October 20, 2011Applicant: Georgetown UniversityInventors: YuYe Tong, Bingchen Du
