Open AccessControl of zeolite microenvironment for propene synthesis from methanol
Optimising the balance between propene selectivity, propene/ethene ratio and catalytic stability and unravelling the explicit mechanism on formation of the first carbon–carbon bond are challenging goals of gre...

Facile heterogenisation of molecular Ti(OSiPh3)4 to form a highly active epoxidation catalyst
The simple grafting procedure of Ti(OSiPh3)4 onto the internal surface of MCM-41 to produce an epoxidation catalyst of high activity and selectivity is described. The presence of the phenyl groups on each titaniu...
