✦ Synopsis

ESR studies using molybdenum enriched in g5hIo have confirmed that tOas is stabilised at hio6* sites at 77 K on silica and alumina supported molybdenum. Warming the MolAlzO3 to 300 ); leads to an incre-ase in the number of (O&ions observed due to electron transfer from seduced molybdenum sites to give additional (O&adsorbed at A13' sites on the sup-port_ Molybdenum is not involved at the adsorption site of (02, on the magnesia supported catalyst.
