제목 Hydrocarbon SCR(Selective Catalytic Reduction) of NO in the presence of water vapor using Pt and tungstophosphoric acid supported on Cubic mesoporous materials
초록 The catalytic activities of tungstophosphoric acid and Pt loaded cubic mesoporous materials(MCM-48 and SBA-1) for the catalytic reduction of NOx with propylene in the presence of water vapor were studied respectively. Before MCM-48 and SBA-1 supported Pt with 1wt% were prepared by incipient wetness impregnation, HPW was loaded between 0 and 60wt%. The structure and the physical properties were characterized by means of powder XRD and BET. The number of accessible Pt atoms of Mesoporous materials supported Pt and HPW containing catalysts was determined by H2-chemisorption and CO-adsorption. Mesoporous materials supported Pt were found to be most active, the loading with HPW led to an improved selectivity to N2 formation and to an enhanced activity in the presence of water.
