The goals of this project have evolved from an investigation of ways of preparing Li and Hall`s Cu-ZSM-5 catalyst using new methods to yield a more robust catalyst, into an investigation of modified Cu-ZSM-5 catalysts for the simultaneous reduction of NO and oxidation of SO{sub 2}. This was not a conscious effort or decision on the part of the investigators, but resulted from a natural evolution of the project. The authors have developed a zeolite synthesis and characterization capability in the group and have prepared impregnated test materials for the investigation of different catalyst precursors. They have prepared different vanadium-impregnated aluminas, for evaluation of the impregnation method, and have succeeded in reproducing the results of Li and Hall`s Cu-ZSM-5 catalyst. This report reviews the progress during the first three quarters of the year, and includes progress from the last quarter. Results are discussed for the Raman spectroscopy of precursors; infrared spectroscopy of vanadium-impregnated alumina; zeolite overlayer on cordierite; reactivity of Cu-ZSM-5; and impregnation of vanadyl acetylacetonate on alumina.
