摘要: Abstract The effect of Electrochemical Promotion (or Non-faradaic Modification Catalytic ActivityNEMCA) was used to promote the Selective catalytic reduction NO by propylene in presence excess oxygen. catalyst form a Rh polycrystalline film, interfaced with Yttria-stabilized-Zirconia (YSZ, an O 2- ion conductor). It found that dramatic changes activity can be obtained under NEMCA conditions, accompanied significant alterations product selectivity. origin electrochemical promotion is discussed light temperature-programmed desorption (TPD) and Work Function (WF) measurements.
