Hydroxy Groups of Zeolites Characterized by IR Fundamental Stretching Bands

Hydroxy Groups of Zeolites Characterized by IR Fundamental Stretching Bands [Pg.73]

From the very beginning of the application of infrared spectroscopy in zeolite science, problems of formation, characterization and properties of surface OH groups attracted the interest of researchers (c [214]), especially as far as acid [Pg.73]

OH groups, so-called Bronsted add sites, were regarded. This interest was particularly stimulated by the close relationship which was suspected to exist between (Bronsted and/or Lewis) acidity and the catalytic behavior of zeolites. [Pg.74]
