摘要: Cu1Ce8Fex–O catalysts for low temperature CO oxidation were prepared by an improved citrate sol–gel method with incorporation of thermal treatment under N2, and characterized the nitrogen adsorption–desorption, XRD, pulse experiments, CO-TPR CO-TPD. When x = 1, Cu1Ce8Fe1–O catalyst shows higher catalytic activity oxidation, reaction 90% conversion (T90) is only 50 °C. The presence Fe in can improve which results from its surface area, smaller crystalline size, larger amounts oxygen species.
