29Si, 27Al and 31P solid-state NMR under magic-angle spinning was used for the study of ultrastable zeolite Y modified with HsPO,. The material is a potential candidate for a new generation of oil-cracking catalysts. Bloch decay and cross-polarization spectra were compared. It was found that amorpho

B MAS NMR proves that incorporation of boron into ZSMJ zeolitic frameworks takes place when boric acid is present in the reaction mixture. The incorporated boron is removed by subsequent calcination, ion exchange, deammoniation, pelletization and time on stream. 'H MA!3 NMR and IR spectroscopy show
