XRD and sem characterization of Cu/Co catalysts supported on Si-Al-zeolite made by a modified sol-gel technique

Cu, Co and Cu/Co catalysts supported on a Si-Al-Zeolite matrix, made by a modified sol-gel method, were characterized by XRD and SEM. The formation of some spinels was identified in some of the samples. Of particular interest were those spinels whose composition included Cu and Co in a mixed oxide. The identification of such structures would explain higher activities in those catalysts.
