Summary of Activities/Interests
Heterogeneous catalysts are used in 90% of chemical processes in the chemical and petroleum industries as ell as in environmental applications. Research in our group focuses in the rational design of novel catalytic materials and novel catalytic reactors. The research approach combines experimental techniques involving advanced high throughput catalysts evaluation techniques, with spectroscopic techniques to characterize the surface and the adsorbed intermediates involved in the reaction (See fig. 1) with theoretical simulations of reactions' pathways. High throughput experimentation includes infrared thermography followed by evaluation in a ten-channel parallel flow reactor. The most active catalysts is studied in detail by kinetics measurements, surface analysis, and microscopic techniques to determine the structure and composition of the surface. Characterization includes scanning probe microscopy (STM, AFM),, x-ray photoelectron spectroscopy (XPS), x-ray diffraction, x-ray absorption fine structure (EXAFS), and gas adsorption. The above information is used to develop a model of the surface that is integrated into either an elementary reaction model or in a Monte Carlo simulation to develop a structure-activity correlation and synthesize new catalysts based on this knowledge.
Current research projects are focused in the catalysis for the production and purification of hydrogen for fuel cells. Hydrogen is produced by catalytic reforming of hydrogen bearing molecules, such as methanol or hydrocarbons (fig. 2), and needs to be purified via the selective oxidation of carbon monoxide without oxidizing hydrogen. We are studying such reaction on new interfacial metal-oxide catalysts that are active and selective at low temperature. We are also studying the generation of hydrogen via the catalytic partial oxidation of methanol in a replaceable cartridge for small fuel cells. A novel method for catalysts preparation involving combustion synthesis is being developed in collaboration with Prof. A. Mukasyan.
Another line of research focuses on the partial oxidation of alkanes to olefins using a new membrane reactor that can operate under autothermal and safe conditions for oxidation reactions. Studies involving the rational design of new selective catalysts by high throughput methods and modeling the membrane reactor are underway for the partial oxidation of propane to acrolein.
A further advanced project involving the microfabrication of supported catalysts is underway with Oak Ridge National Laboratories.
