Abstract

original image

Tungstate turnpike: Mesoporous polymer-supported polyoxotungstate acts as an effective heterogeneous catalyst in the liquid-phase olefin epoxidation using H2O2. The effectiveness is attributed to the optimized hydrophobic/hydrophilic balance within the uniform mesoporous environment. Furthermore, the catalyst can be recycled without significant loss of activity.
