Using Catalytic Nanoparticles to Clean Water
- Type: Archived Webinar
Groundwater remediation through the catalytic breakdown of the undesired contaminants is a more effective and desirable approach than the conventional physical displacement methods of air-stripping and carbon adsorption. Palladium (Pd) catalysts are known to catalyze the hydrodechlorination of trichloroethene in water, at room temperature, and in the presence of hydrogen. We recently discovered that palladium-on-gold nanoparticles (Pd/Au NPs) can be two orders of magnitude more active than Pd supported on alumina on a per-Pd gram basis. In this talk, I will describe our work in improving the feasibility of these NP catalysts for groundwater remediation and in understanding how the gold enhances the Pd catalytic activity so dramatically.
Michael Wong is an associate professor in the Department of Chemical and Biomolecular Engineering, and the Department of Chemistry, at Rice University. He received his B.S. from Caltech (1994), and M.S. (1997) and Ph.D. (2000) from MIT, all in Chemical Engineering. He did his post-doc with G. D. Stucky in the Department of Chemistry and Biochemistry at UC Santa Barbara, before coming to Rice in 2001. His research program lies at the interface of Chemical Engineering, Chemistry, and Materials Science, centered around the concept of engineered nanoparticles. His team of post-docs, graduate...Read more
