摘要:
A novel and highly-efficient hierarchically nanoporous Co-Mn-O/FeOx catalyst fabricated by a hard/soft dual-templating and subsequent deposition-precipitation (HSDT/DP) approach demonstrates unexpectedly high catalytic activity with 100% CO conversion at 75 degrees C and wide temperature window of 75-200 degrees C with complete CO removal for CO preferential oxidation (CO PROX), ascribed to the unique microstructure and strong interaction between finely dispersed cobalt-manganese and FeOx. The excellent catalytic performance allows it to be a practical candidate for CO elimination from H-2-rich stream. (C) 2013 Elsevier B.V. All rights reserved.
