摘要：

Pyridine adsorption was used as a probe of the surface structure of supported molybdate and cobalt molybdate catalysts. The catalysts consisted of a y-Al2O3 support which had been impregnated with various molybdenum loadings ranging from 1.251 to 15% (M0O3). The Raman spectra of the catalyst and of the adsorbed pyridine indicated that a considerable portion of the alumina surface was not covered by molybdenumeven even after molybdenum trioxide was formed. Bronsted acid site and Lewis acid site adsorption were observed for low. © 1979 Taylor & Francis Group, LLC. All Rights Reserved.
