Noble Metal Nanoparticles and Porous Materials for Heterogeneous Catalysis, Separations, and Chemical Sensing
Noble metal nanoparticles are of current interest for a wide range of catalytic applications and offer means to enhance the use of precious (and scarce) metals such as rhodium and palladium. We have pioneered a microwave-assisted synthetic procedure to not only prepare well-defined nanoparticle catalysts, but also to combine two or more metals into alloyed forms, in which in a classical sense. Thus, the alloys formed are entirely new, and present exciting new possibilities for catalysis.
In a second area of research, we are interested in preparing hybrid organic-inorganic porous polymer materials that have unique properties such as the ability to selectively sequester or separate gases from mixtures. Our so-called PCMs (Phosphine Coordination Materials) can be chemically modified in a large variety of ways to decorate the pores with chemical groups that induce improved guest selectivity behavior, small molecule sensing and detection.
