Strong propene adsorption was observed on a commercial Cu-CHA SCR catalyst. Results from CH-TPD, NH-TPD and H-TPR experiments showed that Cu species act as active sites for propene adsorption and contribute significantly to the overall adsorption capacity.Daeyoung Kim...
Experimental and kinetic modeling study of NH3-SCR of NOx on Fe-ZSM-5, Cu-chabazite and combined Fe- and Cu-zeolite monolithic catalysts. Chem. Eng. Sci. 87, 51-66.METKAR, P. S.; HAROLD, M. P. & BALAKOTAIAH, V. 2013: Experimental and kinetic modeling study of NH3-SCR of NOx...
Direct observation of Cu in Cu-chabazite (CHA) zeolite has been achieved by electron ptychography using the Wigner distribution deconvolution. The imaging properties of ptychographically reconstructed images were evaluated by comparing the intensities of six-membered-ring columns of the zeolite with ...
