Infrared studies of the surface acidity of oxides and zeolites using adsorbed probe molecules
The use of infrared spectroscopy to probe the surface acidity of oxides and molecular sieves is reviewed. The experimental requirements and the type and nature of probe molecules available are also discussed. Special emphasis is given to the criteria that have to be met to arrive at a characterization of the solid that is useful for its catalytic application.
متن کاملFourier-Transform Infrared Spectroscopic Comparison of Normal and Malignant Cervical Tissue Cervical Tissue.
Based on the accumulated data, FTIR spectroscopy seems to be a highly sensitive tool in cervical cancer diagnosis. We, therefore, employed this technique in a screening type of research here in Tehran. The purpose of this study was to look for the spectral pattern differences between normal and malignant cervix samples in Iranian women. Through formal and informal announcements, all gynecology ...

متن کاملAcidity of two-dimensional zeolites.
Hybrid quantum mechanics:molecular mechanics (QM/MM) calculations of absolute deprotonation energies are performed with periodic boundary conditions for Brønsted sites of aluminosilicate bilayers with various Al/Si ratios (two-dimensional zeolite). The supercell method is applied and density functional theory is used. Much lower values are obtained (1042, 1069 and 1091 kJ mol(-1) for Al/Si = 1/...
متن کاملThe Synthesis of Zeolites A, X and HS from Natural Iranian Kaolinite and the Study of the Transformation of Zeolites X to HS and Zeolites Y to P by X-ray diffraction and Scanning Electron Microscopy.
Zeolites A, X and HS were synthesized from natural Iranian Kaolinite by alkaline fusion,,followed by refluxing the mixture. The transformation of zeolites X to HS and Y to P were studied at different time intervals by X-ray diffraction and Scanning Electron Microscopy (SEM). It was revealed that in solution, zeolites HS and P are more stable than zeolites X and Y respectively
