Titanosilicate catalysts are of scientific and technological interest because of their ability to be applied to environmentally friendly chemical processes for the liquid-phase catalytic oxidation of a variety of organic compounds, by using H2O2 as a clean oxidant. The medium-sized pore

A novel titanosilicate with MWW topology, Ti-MWW, exhibits a behavior not observed on other titanosilicates such as TS-1, TS-2 and Ti-beta, in that it selectively epoxidizes trans isomers from a mixture of cis/trans alkenes with retention of stereochemistry.
