State and the Catalytic Properties of Cu/ZSM-5 in Selective NO Reduction with Propane
Доклады на конференциях
Catalytic properties of the Cu/ZSM-5 catalyst prepared by ion exchange of the HZSM-5 with aqueous ammonia solution of copper nitrate can be tuned by varying the nature of copper precursor (CC I or CC III). These factors have a significant effect on the copper species located on the surface of zeolite. In the SCR of NO with propane the highest reaction rate per gram of Cu attainable on the catalyst prepared from CC I. This due to the optimum size of Cu2+ oxide clusters, which ensures that a large proportion of the active component is have an optimum degree of covalence for the given process involved in the reaction and the copper–oxygen bonds.
