UR - https://www.unicat.be/uniCat?func=search&query=sysid:7765722 AB - This book provides a comprehensive review of a new generation of selective oxidation titanosilicate catalysts with the MWW topology (Ti-MWW) based on the research achievements of the past 12 years. It gives an overview of the synthesis, structure modification and catalytic properties of Ti-MWW. Ti-MWW can readily be prepared by means of direct hydrothermal synthesis with crystallization-supporting agents, using dual-structure-directing agents and a dry-gel conversion technique. It also can be post-synthesized through unique reversible structure transformation and liquid-phase isomorphous substitution. The structural conversion of Ti-MWW into the materials usable for processing large molecules is summarized. Taking advantage of the structure diversity of the lamellar precursor of Ti-MWW, it can be fully or partially delaminated, and undergo interlayer silylation to obtain a novel structure with larger porosity. In the selective oxidation (alkene epoxidation and ketone/aldehyde ammoximation) with hydrogen peroxide or organic peroxide as an oxidant, the unique catalytic properties of Ti-MWW are described in comparison to conventional titanosilicates such as TS-1 and Ti-Beta.
