Lanthanum-exchanged beta zeolites have been prepared by a solid-state ion-exchange procedure which consists of calcining in static conditions a mechanical mixture of LaCl 3 .7H 2 O and H-beta zeolite. The exchanged samples have been characterized at various steps of their preparation by XRD, BET, F

Solid-state ion exchange between Na and Cs chloride and two NH 4 -b zeolites with different SiO 2 /Al 2 O 3 ratios proceeding during heat treatment in He has been studied. Temperature-programmed gas evolution monitored by mass spectrometry ( TPE/MS ) and thermogravimetric analysis combined with 1-pr
NH 4 Y has been ion exchanged by reaction with solid Rb 2 CO 3 to form RbY. This process has been followed with Xray powder diraction, mass spectrometry and NMR. Both 1 H and 87 Rb MAS NMR are very sensitive to the hydration level of the zeolite and have been used to investigate the solid-state exch
The incorporation of indium(๏ฉ) cations into zeolite beta by reductive solid-state ion exchange has been studied by TPR/TPO techniques, FTIR spectroscopy and a catalytic test reaction (isomerization of m-xylene). Among the hydroxyl groups observed in zeolite beta, those vibrating at 3610 cm-1 (bridge
