Abstract
The reaction sites of CO oxidation induced by 193 nm irradiation were studied in the coadlayer of CO and O-2 on pt(113)=(s)2(111)x(001) arou nd 110 K with the angular and velocity distributions of desorbing prod uct CO2. At low coverages, the CO2 desorption takes place in surface t roughs. On The other hand, three kinds of reaction sites are found at high O-2 coverage, where three additional desorption components, peaki ng along the (111) terrace, the (001) step and the bulk surface normal , become predominant.
