A study concerning the use of Co-containing molecular sieves MFI (ZSM-5) topologies for the styrene oxidation by hydrogen peroxide was performed. The mains products of reaction were benzaldehyde and styrene oxide. A high selectivity to benzaldehyde was observed. The influence of styrene/H2O2 ratio and cobalt content on the styrene conversion and benzaldehyde selectivity has been investigated. The catalytic properties of Co-HZSM-5 samples prepared by wetness impregnation, ion-exchange and oxidant and reductant thermal treatments have been analyzed.
