摘要: Abstract The adsorption and dissociation of CO2 on Rh were studied at temperatures between 80 1200 K with field emission microscopy. For this purpose a new microscope was used which is based image processing. This DigiFEM has very high spatial resolution. Because resolution the surface structure specificity could be monitored in detail. starts (210) followed by (110), (321), (221), (551)-(711) (310). At low coverages around 165 (210). A little below temperature also rearrangement over some desorption take place. Between 235 290 CO recombines O to form desorbs leaving clean 340 K. higher two processes place simultaneously. Following 120 K, 190 Some desorbed after recombination O, but continues importance. Oxygen formed these forced diffuse into bulk Rh. takes Tmax=450 O-atoms start out 600 These are as O2 or RhOx 1000 In order solve taking during study interaction results obtained compared for same tip.
