제목 Mesoporous ceria-metal composite catalysts for CO preferential oxidation reaction in excess H2
초록 The preferential oxidation (PrOx) reaction is an efficient way to purity hydrogen produced by steam reforming of hydrocarbons and alcohols for application in proton exchange membrane fuel cell (PEMFC) for the removal of carbon monoxide, since the presence of CO impedes the H2/O2 reaction by the anode absorption of CO and the consequent poisoning. Optimum fuel cell efficiency requires complete removal of CO (< 10 ppm) from the hydrogen-rich gas feed.  
Catalysts reported for  PrOx reactions are mainly precious metal catalysts, such as Au, Pt, Ru and Rh, exhibiting better low-temperature activity in comparison with base metal catalysts.However, as a noble metal-free alternative, the Cu-Ce-O system is a promising candidate, thanks to its low cost and high selectivity.  
In this work, a series of mesoporous mixed metal oxide catalysts prepared by nano-replication method was evaluated in the PrOx reaction.
