Mesoporous (Cr)MCM-41 and (Cr)MCM-48 molecular sieves: promising heterogeneous catalysts for liquid phase oxidation reactions
Chromium-containing mesoporous MCM-41 and MCM-48 silicate molecular sieves were synthesized and characterized. Unlike the chromium-containing microporous materials, the mesoporous analogues show significant activity for the chosen (ethylbenzene oxidation) reaction even after several recycling or washing treatments.
