Gas-phase radical generation by Ti oxide clusters supported on silica: application to the direct epoxidation of propylene to propylene oxide using molecular oxygen as an oxidant
A new catalytic system consisting of titanium oxide clusters supported on silica was found for radical production at relatively low temperature (similar to 573 K). The clusters give rise to selective oxidation products, such as propylene oxide, through gas-phase chain reactions.
