Study of Supported Catalyst Particles by Tunneling Spectroscopy

It is possible to evaporate a small quantity of metal onto the oxidized aluminum strip of a tunnel junction and then study the adsorption of gases on the resultant supported metal particles. This talk will focus on the adsorption of CO on supported Rh particles. It will also include recent data on the reaction of H2 with this adsorbed CO. Research on this type of system may help in understanding Fischer-Tropsch synthesis and other important catalytic reactions.
