Abstract:
Ruthenium (Ru) nanoparticles incorporated into the pore walls of porous carbon was used as a catalyst in glucose hydrogenation to produce sorbitol. In comparison with other catalysts, including commercial catalysts and catalysts prepared using other methods, the Ru-C nanostructured catalyst displayed higher catalytic activity and stability. These effects were associated with the enhanced contact between the Ru nanoparticles and carbon matrix, as well as the unblocked pores of the catalyst.

Abstract Ru/Al2O3 catalyst was prepared by standard impregnation method. The catalytic reforming performance of Ru/Al2O3 and commercial high nickel/low nickel catalysts on commercial No.0 diesel oil was studied. The regeneration method of carbon-deposited catalyst was also discussed. The results show that commercial low nickel catalyst has poor catalytic activity and stability for diesel, and increasing the water-carbon ratio can slightly improve the conversion rate of diesel. Increasing the reforming reaction temperature and adding methanol additives can effectively improve the catalytic acti

Abstract:
Herein, the Ruthenium nanoparticles (NPs) with the size of 12 nm were decorated on the hexagonal prism silicalite-1 (Ru/S-1) by the gas bubbling-assisted membrane reduction method (GBMR). The adsorption/activation properties are improved for reactant molecules due to the formation of an interfacial structure that enhances the interaction between the Ru NPs and S-1. The Ru/S-1 catalyst displays the highest catalytic activity (T50 = 356 °C) and CO2 selectivity (SCO2m = 99.9%). Moreover, no obvious deactivation was observed over the Ru/S-1 catalyst even after five cycles, and the values of T50 an

To improve the DEFC power density, high temperature operation (150–200 °C) has been suggested to promote the complete oxidation of ethanol.

Abstract:
Diesel is one of the best hydrogen storage systems, which has very high volumetric density [kg H2/m3] (&gt;100) and gravimetric density [%H2] (&gt;15). Several catalysts were selected for diesel reforming. 3 catalysts (Pt on gadolinium doped ceria, Rh and Ru on the same support, Patent for catalyst formulation of Argonne National Laboratory in U.S.A) and 2 commercial catalysts (FCR-HC14 and FCR-HC35, Su¨d-Chemie, Inc.) were used to reform diesel. Pt catalyst showed the best performance. Effects of operating conditions such as temperature, O2/C and H2O/C on ATR (autothermal reforming) were inve

Abstract:
The authors reveal the dominant chemical reactions and the optimum conditions, supposing the design of ethanol steam-reforming reactors. Specifically speaking, experiments are conducted for Cu/ZnO/Al2O3 catalyst, together with those for Ru/Al2O3 catalyst for reference. Using a household-use-scale reactor with well-controlled temperature distributions, the authors compare experimental results with chemical-equilibrium theories. It has revealed by Shinoki et al. (2011) that the Cu/ZnO/Al2O3 catalyst shows rather high performance with high hydrogen concentration CH2 at low values of reaction temp

Abstract:
A through-chip porous Ru-Pt catalyst layer was fabricated on a Si wafer and a novel miniature DMFC (Direct Methanol Fuel Cell) was realized. Recently, we found that porous noble metal layer can be synthesized on Si substrate by immersion plating on a porous Si. In order to realize a DMFC with our novel structure, a porous Ru layer was synthesized on the Si substrate using the immersion plating on the porous Si, then Pt was deposited by galvanic replacement reaction on the porous Ru. The porous Ru-Pt structure showed catalytic activity on methanol oxidization. A through-chip porous Ru-Pt layer

Abstract:
We report a combinatorial and high throughput catalyst optimization of ternary Pt-Co-Ru alloy electrocatalysts for the oxidation of methanol in Direct Methanol Fuel Cell anodes. A densely sampled ternary Pt alloy catalyst library was prepared and electrochemically tested in parallel for catalytic activity. A composition-activity map was obtained from which suitable catalyst candidates with improved activity were identified. Then, high throughput methods for evaluating corrosion stability of the alloy catalysts were developed based on structural and compositional criteria. Finally, combining st

Abstract:
Hydrogen is often considered as a promising alternative to fossil fuels, however its low boiling point and diffusivity cause a huge challenge for storage and transport. Therefore an alternative fuel like ammonia, containing 17 wt.% hydrogen with a higher boiling point, seems a very promising solution for hydrogen storage and transport. In this paper, ammonia synthesis via the most widely used Haber-Bosch process has been investigated. A computational fluid dynamics (CFD) model is developed for a lab-scale reactor, incorporating the modified Temkin kinetic model describing the complex catalytic
