The influence of zeolite nature on catalytic activity of Co-containing systems of CO oxidation was investigated. It is established that the activity of catalysts increases in the order 10%Co-NaA < 10%Co-NaM < 10%Co-NaZSM-5(37) < 10%Co-NaZSM-5(69). The cobalt spinelCoCo2O4 formed on the surface of zeolite supports is established to be an active phase. The TPR-H2 study of Co-zeolite systems showed that the content of cobalt cations with high reducibility in the surface layer was the largest for the most active catalyst Co-NaZSM-5(69).
