The coating-type Platinum catalysts on activated carbon were prepared using the method of incipient-wetness impregnation and examined for the catalytic oxidation activity of ethanol at ambient temperature and atmosphere pressure. The relationships of impregnant, impregnation time and calcination temperature on catalytic activity of Pt/AC were investigated, and the optimal preparation conditions of Pt/AC were: impregnant (Ethylene glycol 250mL, deionized water 50mL), impregnation for 60min, calcination at 240°C for 240min. The experimental results based on the Pt/AC showed that the Pt/AC catalyst was able to remove ethanol efficiently from humidity condensate. With the analysis of XPS and SEM, the active component Pt of catalyst was existed as the type of structure Pt⁰, and Pt particals on activated carbon had high dispersion and excellent catalytic oxidation activity.
