NO adsorption on a Pt(100)-(hex) surface and NOads reaction with hydrogen at 300 K have been studied by HREELS, LEED, TDS and isothermal desorption. NO adsorbs in molecular form, its molecules gathering in islands with a high local coverage. Surface reconstruction into a (1 × 1) phase proceeds within the boundaries of islands. Reaction NO + H2 is performed via NOads previous heating in vacuum at Th = 375–425 K. Kinetics of NOads titration appears to be autocatalytic. Nitrogen is the major reaction product.
