Polymer Program SeminarNanoparticles and Nanostructures for Catalysis and Sensing SUNY Binghamton Friday, April 9, 2004 11:00 am , IMS Room 20 We have been exploring a general bottom-up pathway for fabricating nanostructured materials from metal and alloy nanoparticles. This pathway entails molecularly-engineered processing of particle size, shape, composition and surface properties and molecularly-mediated assembly of nanoparticles via hydrophobic, covalent, hydrogen-bonding, or multidentate coordination. The electronic conductivity, interparticle spacing, chemical specificity, dielectric medium, framework binding and molecular channeling properties of the nanostructured materials are fine-tunable for constructing chemical/biological sensing interfaces and for preparing highly-active catalysts. Recent results in the exploration of the nanostructured sensing arrays for detecting volatile organic compounds and ionic species and in the investigation of the nanostructured catalysts for fuel-cell anode and cathode reactions will be discussed.
