Studies on the formation and structure of molecular clusters of (CdS)4 in zeolite y by in-situ IR and 113Cd MAS NMR

Summary 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 113 Cd MAS NMR.
