Results obtained by i.r. and e.p.r, spectroscopy show that at least two gallium-containing extraframework species differing in location, chemical nature, and acidic behavior are present in gallosilicate isostructural with ZSM-5 zeolite. Both species are formed in larger amounts by gallium release fr
The specific behavior of HY in some steps that possibly occurred in the selective catalytic reduction of NO by hydrocarbon (HC-SCR) was investigated. Experimental results indicated that the activity of HY for NO oxidation to NO 2 was much lower than those of the pentasil zeolites (HZSM-5, HFER and H
