摘要：Ce-Co catalyst was prepared by template method (denoted as Ce-Co-T) and co-precipitation method (denoted as Ce-Co-C) for element mercury oxidation. Structural results showed that Ce-Co-T had a much larger BET surface area (220.01 m(2)/g) and uniform mesoporous channels along with uniform particle size which could lead to more surface active sites. XPS showed that Ce-Co-T had more surface active oxygen species resulting in a better redox property. Compared with Ce-Co-C, Ce-Co-T had a much better Hg-0 oxidation efficiency which maintained above 95% under a high GHSV (180, 000h(-1)) in the range 150-350 degrees C.
