    Facile Preparation of Nanoporous PtCu Alloys for Preferential Oxidation of CO in Hydrogen-Rich System
    摘要:
    Nanoporous (NP) PtCu alloys were straightforwardly fabricated by a simple dealloying method, characterized by bicontinuous interconnected nanosponge structure with the typical size around 10 nm. By controlling the time of selectively etching PtCu source alloy, NP-PtCu alloys with three different compositions were easily obtained, whose catalytic activities were evaluated towards the preferential oxidation of CO (PROX) as a function of the residual Cu content. The presence of H-2 has little influence on the CO oxidation activity over PtCu catalysts for PROX reaction. NP-PtCu catalysts with three bimetallic compositions exhibit distinct PROX catalytic performance along with different CO conversions and selectivity. The maximal values of CO2 selectivity on Pt60Cu40 and Pt78Cu22 catalysts could reach as high as 70-75% at the temperature as low as 70 degrees C. Compared with Pt43Cu57 and Pt78Cu22, Pt60Cu40 sample shows the superior catalytic activity for PROX reaction with the higher CO conversion and CO2 selectivity in a wide temperature range of 50-160 degrees C. Moreover, NP-PtCu catalyst has excellent catalytic stability with almost no activity loss and structure coarsening upon consecutive cycling tests.
