摘要: Abstract D- (H)-covered Pt(100) surfaces were exposed to thermal H (D) atoms at 90 K and the kinetics of reaction product formation was measured simultaneously with atom exposure. HD D 2 (H ) observed as products. The these products differ from in analogous reactions on Pt(111) Pt(110) surfaces, give further evidence for structure sensitivity abstraction reactions. can be explained by assuming heterogeneity reactivity sticking.
