摘要：
Employing metal-organic frameworks (MOFs) as precursor, a series of CuO/CeO2 catalysts with well-dispersed copper species were synthesized and applied for preferential CO oxidation in H-2-rich stream. The catalyst with 5 wt.% Cu loading calcined at 600 degrees C for 6 h exhibited an excellent catalytic activity. The high activity of the CuO/CeO2 catalysts indicated that MOF precursor played a key role for improving the dispersion of metal active sites. (C) 2012 Elsevier B.V. All rights reserved.
