Abstract: A series of FeO x-T supports were prepared by thermal treatment at different temperatures, and
then FeO x-T supported Pt (Pt/FeO x-T) catalysts were prepared by a facile colloid deposition method. Their
catalytic properties were investigated in the oxidation of formaldehyde at ambient temperature. These
catalysts were characterized by XRD, BET, H 2-TPR, FTIR and TEM. The results showed the thermal
treatment temperature could affect the BET surface area and oxidation-reduction property of FeO x, the
amount of surface hydroxyl groups of Pt/FeO x-T, and the interaction between Pt species and FeO x. The
results indicated that when FeO x was thermally treated at 100 ℃, the prepared Pt/FeO x-100 catalyst with a
Pt loading of 1.5wt% had high catalytic activity. The conversion of formaldehyde over this Pt/FeO x-100
could reach 96.2% at a relative humidity (RH) of 55% and ambient temperature (25 ℃).
