Titanium silicalite-1 (TS-1) is a milestone heterogeneous catalyst with single-atom tetrahedral titanium incorporated into silica framework for green oxidation reactions. Although TS-1 catalysts have been industrialized. the strategy of direct hydrothermal synthesis usually produces catalysts with low catalytic activities. which has still puzzled academic and industrial scientists. https://www.getpureroutine.com/quick-grab-poise-pads-overnght-bulk-16-supply-mega-offer/
