Abstract

1. A gamma-resonance spectroscopic study has been made of systems obtained by impregnating molybdenum disulfide samples with solutions of⁵⁷Fe(NO₃)₃·9H₂O in different solvents (formamide, acetone, water) and subsequently sulfidizing them. After a catalyst is sulfidized, most of the iron is in the form of magnetic sulfides, and the remainder is present in the form of the paramagnetic ions Fe²⁺ and Fe³⁺. 2. The catalytic activity of these systems in the hydrogenation of o-xylene in the presence of thiophene, which depends on the type of solvent, is due to the paramagnetic iron ions that form a structure in combination with the MoS₂; the activity increases with increasing amounts of Fe³⁺ ions.
