Sonochemical Synthesis of Mesoporous Titanium Oxide with Wormhole-like Framework Structures

Ultrasound irradiation is proving to be an excellent method for the synthesis of mesoporous oxides. Here is reported the preparation of titania containing a framework of wormholes—a structural motif of importance for catalysis. Using ultrasonication with a long-chain organic amine as a structure-directing agent, the synthesis was complete in a few hours (the Figure shows particles of the as-prepared material).
