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 H 2 O 2 as an oxidant.
