Preparation of Hierarchical Ti-Sil-BEA Zeolite by Silanization Modification for the Application in Dicyclopentadiene Epoxidation Reaction.

The pore-expanding modification of zeolites is an important means to improve their catalytic performance. This study demonstrates the postsynthesis of Ti-Sil-BEA zeolites via silanization-modified parent BEA zeolite and its application in catalyzing epoxidation reactions of dicyclopentadiene (DCPD). The zeolites were characterized by BET, X-ray diffraction, scanning electron microscopy, transmission electron microscopy, UV-vis spectroscopy, and X-ray electron spectroscopy.

From bench to industry, the application of all-inorganic solid base materials in traditional heterogeneous catalysis: a mini review.

Acids and bases generally occur in pairs as concepts, and a large number of catalytic reactions can be considered as interactions between acids and bases. Many chemical reactions are a combination of acid-catalyzed processes and base-catalyzed processes, and thus it is particularly important to study and explain the mechanisms of acid-base synergy or acid-base interactions. However, compared to the in-depth research on acid catalysts, there is a lack of research on solid bases.
