摘要：

With an analogous structure to an MWW lamellar precursor, a titanosilicate (denoted Ti-YNU-1) has been developed by using a postsynthetic acid-treatment and calcination procedure (see scheme). The material behaves as a large-pore zeolite, showing high activity, selectivity, and stability towards the liquid-phase epoxidation of bulky cycloalkenes using H2O2 as an oxidant.
