Abstract
Silicon has been isomorphously substituted by aluminium and gallium in the microporous titanosilicate ETS-10 to produce ETAS-10 and ETGS-10 respectively. For aluminium substitution a series of samples have been prepared with Al/Ti ratios ranging from 0.10 to 0.48. Both aluminium and gallium substitute exclusively in tetrahedral silicon sites in a m anner which avoids Ti-O-Al and Ti-O-Ga linkages. Based upon detailed a nalysis of solid-state NMR spectra, models for the ordering of alumini um in ETAS-10 are discussed.
