✦ Synopsis

It is shown that the reaction between NO and CO on Pt(100) is autocatalytic and probably involves a surface species which accelerates the reaction. Temperature-programmed desorption (TPD) of co-adsorbed NO and CO yields complete reaction, with N2 and CO2 desorbing simultaneously in sharp peaks at =410 L. Isothermal desorption also yields rates characteristic of chemical autoutalpsis.
