| Abstract: | Iron hydroxyphosphate as support for Pt catalysts is explored for preferential oxidation of CO using simulated reformate gas mixture in the temperature range 40-240 °C. The CO oxidation activity and selectivity at low reaction temperatures are enhanced on addition of H2O but decrease at high temperatures due to the reverse water gas shift reaction. X-ray diffraction patterns of the supported and unsupported catalysts show very weak diffraction lines due to the Fe5(PO4)3(OH)5 phase. The chemical composition of this phase on the catalyst surface has been confirmed by X-ray photoelectron spectroscopy results. |
