Heterogeneous radiolysis of CO2 in the presence of zeolites

Abstract Radiation catalytic activity of different zeolites Ca A , Na X , Na Y , LiNa Y , Ba M in CO 2 radiolysis has been investigated. This has led to studies in the catalyst porosity, the number of adsorbed CO 2 molecules and adsorption forces on their surface on the yield of CO 2 radiolysis products. A mechanism has been suggested for the observed CO 2 radiolysis processes over different zeolites. One of the possible ways to increase CO yield in radiolytic processes of CO 2 decomposition is to use various types of catalyst. (1–3) Therefore, the development of a scientific basis for appropriate catalyst selection is becoming of particular interest. For this purpose, heterogeneous CO 2 radiolysis in the presence of high-silica zeolites has been studied in this paper.
