Preparation of supported Cu/ZSM-5 zeolite films for DeNOx reaction

Abstract This work reports the in situ synthesis of ZSM-5 zeolite films on cordierite and the performance of a Cu/ZSM-5-coated monolithic catalyst in the lean NO x reduction reaction. At the end of the hydrothermal crystallization, a zeolite/cordierite composite was obtained which consists of a continuous zeolite film that strongly attaches to the sustrate surface. The monolithic catalysts so prepared are active for the reduction of NO.
