Highly dispersed α‐Fe 2 O 3 /NaY, NiO/NaY, and CuO/NaY catalyst systems were prepared by impregnation method. Dispersion thresholds of the transition metal oxides on NaY zeolite were determined by XRD phase analysis. The dispersion capacities of the transition metal oxides on NaY zeolite are much lower than that estimated on the basis of a closed packed monolayer in the micro pores. The catalytic activity and selectivity of the highly dispersed oxide catalyst systems for ethylbenzene and cyclohexane dehydrogenation reactions were reported.
