英文摘要the accessibility and acidity of hzsm-35 zeolite were studied by high-resolution solid-state mas nmr spectroscopy after adsorption of deuterated pyridine or trimethylphosphine as probe molecules. the results showed that the probe molecules could enter both the ten-membered ring (10-mr) channels and eight-membered ring (8-mr) cavities. however, the diffusion into the 8-mr cavities was very slow and it took a long time to reach the adsorption equilibrium at 300 degrees c. after adsorption of deuterated pyridine, (1)h mas nmr spectra showed that there were two types of bronsted acidic sites with different strength in both the 10-mr channels and 8-mr cavities. after adsorption of trimethylphosphine, the (31)p mas nmr spectra indicated that there were lewis acidic sites in hzsm-35 zeolite, but their strength and amount were less than the bronsted acidic sites.
