摘要：

The spatial and velocity distributions of desorbing products were measured in the CO oxidation on Pd(110) and reconstructed Pt(110)(1 x 2) surfaces by means of a cross-correlation time-of-flight technique combined with angle-resolved thermal desorption. On Pd(110), a clear anisotropy was observed in both distributions. It is well correlated with the reaction site symmetry. On Pt(110)(1 x 2), both the desorption flux of CO2 and the translational temperature are maximized around the terrace normal, confirming that the reaction occurs on declining terraces.
