An. Il'Ichev et al., Effect of copper cations on the formation of radicals in the adsorption ofolefins and benzene on Cn/ZSM-5 zeolite, MENDELEEV C, (1), 1999, pp. 27-29
Isolated Cu2+ cations in ZSM-5 zeolite produced oligomeric radicals from pr
opylene and did not result in the formation of radicals in the adsorption o
f ethylene and benzene.
