摘要
A method is proposed for the preparation of Ru/ZSM-5 catalysts using substituted and non-substituted ruthenocenes. To this end, the following complexes have been synthesized and characterized: dimethyl-1,1′; diphenyl-1,1′; dibenzoyl-1,1′, and monobenzoyl ruthenocene. Results of ESC A intensity ratio and ir of adsorbed pyridine show differences in the surface segregation of Ru as well as in the cationic exchange of Ru with Brønsted acid sites of the zeolite, when the catalyst is prepared using ring-substituted ruthenocene instead of ruthenocene itself. The binding energies of Ru 3d5/2 measured by ESCA are discussed.
