摘要：
Series of ZrAl- and SnAl-silicate hierarchical zeolites of the BEA structural type have been synthesized by hydrothermall method, and their acidic and catalytic properties in the reaction of cyclohexanone oxidation with hydrogen peroxide have been investigated. For SnAl-BEA zeolites, the conversion of cyclohexanone into ε-caprolactone increases as the tin content in the samples increases in the range of 0.83-2.5 mole%Sn and the concentration of Lewis acid sites increases, while for ZrAl-BEA zeolites, the maximum value of conversion (80%) is achieved for the sample with 1.33 mole % Zr.
