英文摘要	Co-oxidation of CO and H₂ or oxidation of H₂ in the presence of CO was first achieved at low temperatures(0–20 ℃) over single-component catalysts (Pd/FeO_x) at a space velocity of 15,000 ml g-1cat h-1. A systematical study of FeO_x- and Al₂O₃-supported Pd catalysts is carried out by means of STEM, TEM, XRD, XPS, Mössbauer spectra, and time-resolved CO titration. Highly dispersed Pd nanoparticles with size 1–1.8 nm over 5.4 wt% Pd/FeO_x are confirmed by HAADF-STEM and HRTEM. Time-resolved CO titration, Mössbauer spectra, and XRD and XPS results suggest FeO_x support supplying active oxygen is involved in the oxidations. Particle size effect and oxygen supply from FeO_x support are speculated to be the main reasons for the excellent performance of Pd/FeO_x in co-oxidation of CO and H₂ or oxidation of H₂ in the presence of CO.
