Abstract

The interaction of NO with alumina-supported catalysts prepared from Cr(CO)6, Mo(CO)6, and W(CO)6 has been investigated by means of infrared and EPR spectroscopy. Adsorption of NO on Cr(CO)6---Al2O3 produces Cr2+ and Cr3+ nitrosyl species identical to those found on reduced CrO3---Al2O3. A paramagnetic Mo+NO+ species has been detected on Mo(CO)6---Al2O3, but the majority species on this catalyst is a Mo4+ dinitrosyl complex identical to that found on MoO3---Al2O3. A corresponding W4+ dinitrosyl complex is formed on W(CO)6---Al2O3.
