The transformation from Pt(110)(1x2) to (1x1) is first reported through angular and velocity distributions of desorbing product CO2. These distributions were examined in steady-state CO oxidation on Pt(110) in a wide range of surface temperature and reactant pressures with cross-correlation TOF techniques. Both distributions changed sharply at the transformation point.
