catalyst these peaks were not observed. This was typical for the formation of large transition metal complex ion in the supercage of zeolite Y (Fan et al. 2003).This can also be verified by FTIR spectroscopy. Figure 7.2. XRD patterns of NaY zeolite (a), ligand (H2 salpn) (b), BiNaY, Bi (salpn)- NaY (c), Ni NaY, Ni (salpn)-NaY (d), Zn NaY, Zn (salpn)-NaY (e), Cr NaY, Cr (salpn)-NaY (f), Fe NaY, Fe (salpn)-NaY (g) (cont.on next page) 41
