Engineering High Surface Area Catalysts for Clean Tech Applications

McIlroy D.N., Corti G., Cantrell T., Beaux M., Prakash T., Norton M.G., Washington State University, US

Since catalytic performance is a limiting factor for many essential elements of the hydrogen economy, the need for improved catalysts is great. One-dimensional (1D) nanomaterials are ideal catalysts because of their large surface area to [...]

A Novel Anode Electrode for Direct Borohydride Fuel Cell

Kim K-J, Bernas R., Miley G.H., Luo N., Yang X., University of Illinois, US

As part of the development of a portable fuel cell using direct sodium Borohydride fuel, deposition methods of the catalysis on the diffusion layer have been studied. In earlier studies catalyst deposition onto a porous [...]

Molecular approach for the synthesis of supported nanoparticles on active carbon using noble metal clusters

Willocq C., Vidick D., Hermans S., Delcorte A., Bertrand P., Dubois V., Devillers M., Université catholique de Louvain, BE

A molecular approach was envisaged for the preparation of nanoparticles supported on carbon. The support was first treated in order to build suitable anchors for organometallic compounds on the surface. Palladium clusters of various nuclearities [...]

In-situ incorporation of Pd-MPTES complex in nanostructured silica

García Martínez J., Carrillo A.I., Linares N., University of Alicante, ES

Recently, we described a simple method to incorporate metal nanopaticles in porous materials by functionalization of nanoparticles with trialkoxysilanes. This strategy is based on three steps: first, the metal nanoparticles were produced by controlled reduction [...]

Destruction of Organophosphate Agents by Recyclable Catalytic Magnetic Nanoparticles

Bromberg L., Hatton T.A., Massachusetts Institute of Technology, US

Organophosphorus pesticides and warfare agents are not readily hydrolyzed in aqueous media without applying extremes of pH, heat, or bleach. We show that suspensions of magnetite (Fe3O4) nanoparticles modified with a common antidote, 2-pralidoxime (PAM), [...]

8nm cerium oxide as a fuel additive for fuel consumption and emissions reduction

Wakefield G., Gardener M., Oxonica Materials Ltd, UK

8nm cerium oxide is surface functionalised for diesel compatibility and added to fuel at a level of 5-8ppm. Static engine tests and large scale field trials show that engine fuel consumption is reduced by 5-8% [...]

Two-nozzle flame synthesis of tailored Pt/Ba/Al2O3 nanoparticles for NOx storage-reduction

Strobel R., Piacentini M., Maciejewski M., Baiker A., Pratsinis S.E., ETH Zürich, CH

NOx storage reduction (NSR) catalysts are applied for the abatement of NOx from engines operating under lean conditions, where conventional TWC catalysts are inefficient. Here, a novel two-nozzle flame spray pyrolysis (FSP) process was developed [...]
