FIELD: chemistry.
SUBSTANCE: describes the non-activated Renei catalyst on the carrier. The catalyst comprises an organic polymeric carrier material and Renei alloy particles. The Renei alloy particles are supported on a polymeric carrier material, where substantially all the particles are partially embedded in the carrier material. In this case, the particles of the Renei alloy are distributed unevenly in the catalyst and the concentration of particles in the surface portion of this carrier is greater than the concentration of the particles of the Renei alloy in the middle part of this carrier. Activation of the catalyst is carried out by activating a non-activated supported catalyst with a caustic aqueous solution.
EFFECT: preparation of Renei catalyst with high activity, good selectivity and easy extraction of metal.
