Resumen
Microreactors based on Cu, Ce oxides dispersed onto zeolite films grown on brass microgrids were developed. Secondary synthesis conditions were regulated in order to obtain thin, homogeneous and adherent coatings of mordenite to which Cu and Ce were later incorporated. The systems were characterized by XRD, SEM-EPMA, H2-TPR, LRS and XPS. The catalytic coatings were mechanically and chemically stable under reaction. Cu, Ce/zeolite microreactors were evaluated in the CO total oxidation (COTox) and in the preferential CO oxidation (COProx) showing a superior performance when compared with the same powder catalyst.
