摘要: A silica-pillared layered niobate (Si-Nb3O8) has been prepared by intercalating with NH2(CH2)3Si(OEt)3. The results of XRD and BET measurement showed that the obtained product was a porous material high specific surface area thermal stability, its structure remained unchanged after treatment 5 vol% water vapor at 500 °C for 3 h. Using Si-Nb3O8 as support, 2 wt% Cu/Si-Nb3O8 catalyst impregnation Cu(NO3)2 solution catalytic reduction NO CO examined. had good activity selectivity, pretreatment could obviously improve conversion reduction, while selectivity to N2 almost kept unchanged.
