Pd–Fe–Ox catalysts for low temperature CO oxidation were supported on SBA-15, CeO2 nano-particles with rich (111) facets and CeO2 nano-rod with rich (200) facets, and characterized by X-ray diffraction, low-temperature nitrogen adsorption, transmission electron microscopy and temperature-programmed reduction. The results showed that when CeO2 nano-rod was used as a support, Pd–Fe–Ox catalyst exhibits higher activity (T100 = 10 °C), resulting from the rich (200) facets of CeO2 nano-rod, which leads to a formation of large numbers of the oxygen vacancies on the surface of Pd–Fe–Ox catalysts.
