摘要: Hybrid sol–gel catalysts of zinc hexacyanocobaltate and SiO2 were prepared by co-precipitation the double metal cyanide with silica. at moderately acidic conditions showed best performance respect to activity, selectivity stability. The hybrid materials displayed high catalytic activity for copolymerisation styrene oxide carbon dioxide (up 650 molSO (molZn h)−1) productivity (575 gPolymer gCatalyst−1). They also good polymeric product (80–87%), while only little cyclic carbonate was formed as side product. A detailed electron microscopy study that active phase consisted thin platelets containing metals in a molar ratio nZn/nCo = 2.1, whereby closely associated
