Chemisorption and reactivity studies of small molecules on rhodium surfaces

Technical Report ·
OSTI ID:5777581

The chemisorption of H/sub 2/, O/sub 2/, CO, CO/sub 2/, NO, C/sub 2/H/sub 2/, C/sub 2/H/sub 4/, and C was studied on the clean Rh(111), (100), (755), and (331) surfaces. Low-energy electron diffraction (LEED), Auger electron spectroscopy (AES) and thermal desorption mass spectroscopy (TDS) were used to determine the size and orientation of the unit cells, desorption temperatures and decomposition characteristics for each adsorbate. All of the molecules studied readily chemisorbed on all surfaces and several ordered surface structures were observed. 190 references (JFP)
