摘要：
The acidity of various MoO3-SiO2 and WO3 catalysts has been measured by means of ammonia adsorption. Whereas the acidity of silica and pure metal oxides is very low, an increase of surface acidity results from a reaction between silica support and metal oxides. A significant correlation between surface acidity and catalytic activity for aromatization of lower olefines could be found. © 1979 Akadémiai Kiadó.
