英文摘要Acidic properties of ZrO(2), SO(4)(2-)/ZrO(2), SnO(2), and SO(4)(2-)/SnO(2) were studied by solid-state NMR spectroscopy. (1)H MAS NMR indicated that SO(4)(2-) was able to react with the hydroxyl groups of ZrO(2) and SnO(2), leading to 4 the formation of new acid sites. (1)H, (13)C, and (31)P MAS NMR spectra of adsorbed probe molecules indicated that both Bronsted and Lewis acid sites were present on SO(4)(2-)/ZrO(2), but only Bronsted acid site existed on SO(4)(2-)/SnO(2). Acid strength of SO(4)(2-)/SnO(2) was stronger than that of SO(4)(2-)/ZrO(2). Both of them were slightly stronger than that of HZSM-5, but still weaker than that of 100% H(2)SO(4).
