Abstract

Ujawniono sposób otrzymywania materiału zeolitowego z fazą srebrową, charakteryzującego się kontrolowaną dyspersją srebra oraz pożądaną lokalizacją w strukturze zeolitu. Uzyskiwany materiał może być stosowany jako wydajny i trwały katalizator, zwłaszcza w syntezie organicznej.A method for obtaining a zeolite material with a silver phase, characterized by controlled silver dispersion and desired location within the zeolite structure, is disclosed. The resulting material can be used as an efficient and durable catalyst, particularly in organic synthesis.
