概要

• 論文の詳細を見る

• The reaction sites in the thermal and photolytic CO oxidation on Pt(s)2(111)x(001) were examined through analysis of the angular and velocity distributions of desorbing product CO_2. In the former, the CO_2 desorption is sharply collimated but fairly shifted from the site normal, although the reaction proceeds on hollow sites of (100) and (111) patches. On the other hand, CO_2 produced in the photo-reaction is desorbed sharply along the (100) and (111) plane normal. This difference in the collimation is explained by reducing surface smoothing effect due to high velocity of desorbing CO_2.reaction siteangular distributionstepped surfacesthermal desorptionphoto-induced reaction
