摘要：

Modern trends in IR-spectroscopic characterization of acid (Bronsted and Lewis) and basic (framework oxygen) sites in zeolites and oxide catalysts are reviewed. Besides the enhancement of the sensitivity of IR spectroscopy due to application of Fourier-transform or diffuse-reflectance techniques, the progress in characterization is shown to be related to the broadening of the spectral range (investigation of overtones, combination bands, and low-frequency modes) and the use of new non-traditional probe-molecules for identification of acid and basic sites. A number of examples are given, which illustrate the advantages of the new spectroscopic approaches and probes.
