Pt/Pd Nanoparticle Catalysts•The most common application of Pt/Pd nano-catalysts is the automotive catalyticconverter.•Also used in polymers, textiles, and solar energy materials•A major point of research in Pt/Pd nano-catalyst research is in the biomedical field•Platinum based metal nanoparticles are critical in fuel cell technology where cheapeffective catalysts are in great demand.http://image.truckinweb.com/f/8330265/0708tr_22_z+2001_ford_f150_super_crew+broken_catalytic_converter.jpg
Gold Nanoparticle Catalysts• Gold as a material ischemically inert(stable)and generally regardedas a poor catalyst.• Masake Haruta resentlypublished a paper in ascientific journaldescribing how goldcan be an effectivecatalyst at nanoparticlesizes.• Haruta argues that thecatalytic properties ofgold depend on threemain factors:1. Contact Structure2. Support Selection3. Particle Sizehttp://www3.interscience.wiley.com/cgi-bin/fulltext/104529618/main.html,ftx_absImage shows catalytic activity for theoxidation of H2 as a function of temperature.Traditional Gold requires a high h temperature tto even become a poor catalyst.
