The epoxidation of allyl alcohol with in situ generated hydrogen peroxide was performed in an electrochemical cell with a trickle-bed electrode, composed of carbon black, graphite, PTFE and titanium silicalite-1 (TS-1) as heterogeneous epoxidation catalyst. Mass transport in interaction with the catalytic activity limits the epoxidation rate. The conversion of allyl alcohol increases with increase in the content of epoxidation catalyst in the electrode. In contrast, the specific reaction rate decreases due to the reduced accessibility of active sites in the catalyst.
