Gold Nanoparticle Catalystshttp://www3.interscience.wiley.com/cgibin/fulltext/104529618/main.html,ftx_abs• Haruta proved that gold can be a very potent catalyst when impregnated on other surfaces.• Impregnating various metals with gold nanoparticles resulted in an effective catalyst for the following types ofreactions:1. Complete Oxidation2. Oxidative decompostion3. Redecution of NOx4. Oxidation or reduction of COx5. Selective oxidation6. Selective Hydrogenation7. HydroChlorination• Percent of conversion is highly dependany on Catalytic Metal Loading Percent and Mean Particle Diameter.
Gold Nanoparticle Catalysts• Effective particle size for goldNanocatalyst is less than 5 nm.• Decrease of the surface arecoordination number and themobility of surface gold atomslead to greater reactivity.• Contact structure is importantbecause it governs theavailability and order of thegold atoms.• Gold nanoparticle catalystsremain effective at lowtemperatures.http://www.livbit.com/article/wp-content/uploads/2008/12/gold-nanoparticles.jpg
