摘要

With in situ IR. two different CO adsorption bands were detected on various chemical state gold catalysts. One band is attributed to the linear CO on an oxidized gold catalyst(2100 cm^-1), the other one is ascribed to the bridged CO on metallic gold (2085 cm^-1). CO pulse reaction showed that Au/Fe₂O₃ catalyst had a room-temperature activity even in the presence of moisture. The produced CO₂ was detained and more easily desorbed from supported gold catalyst than support oxide. TPD-IDT results indicated that the O₂^- superoxide jons are the possible active oxygen species.
