STUDIES ON THE FORMATION AND STRUCTURE OF MOLECULAR CLUSTERS OF (CdS)4 IN ZEOLITE Y BY in-situ IR AND 113Cd MAS NMR

摘要

The formation of molecular clusters of (CdS)4 in zeolite Y was studied by the changes of HF-OH and LF-OH bands of Y zeolite measured with in-situ FT-IR at different stages of preparation such as exchange, thermal treatment, sulphuration etc., and the coordination structure was evidenced by the results of 113Cd MAS NMR.
