Abstract

Oxygen TPD revealed that the adsorption of water vapor at 278 K promoted the desorption of the preadsorbed oxygen at 793→278 K over NiO and Fe2O3. Preadsorption of water vapor at 473 K brought about a marked enhancement over Fe2O3 and a slight increase over CuO in the adsorption of oxygen at 473→278 K.
