Abstract:

Transmission infrared spectroscopy has been used to search for the chemisorptive-stabilization of formyl HCO on Al2O3-supported Rh surfaces. Formaldehyde H2CO and glyoxal HCO2 have been used as potential sources of HCO. In addition, chemisorbed CO on Rh has been treated with atomic deuterium in an attempt to produce DCO. None of these routes have led to spectroscopically detectable levels of formyl adsorption at temperatures near or above 100K. These results suggest that the formyl intermediate may not be a stable surface species on Rh in CO-hydrogenation chemistry. Author
