Synthesis of Fe-MCM-41 from silatrane and FeCl 3 via sol–gel process and its epoxidation acivity

An iron-containing mesoporous molecular sieve, or Fe-MCM-41, was successfully synthesized the via sol–gel technique using silatrane and FeCl 3 as the silicon and iron sources, and was characterized using various techniques. Many factors were investigated, namely, reaction temperature and time, calcination rate, and iron amount in the reaction mixture. It was found that the optimum conditions in which to synthesize Fe-MCM-41 was to carry out the reaction at 60 °C for 7 h using a 1 °C min −1 calcination rate and a 550 °C calcination temperature. The catalytic activity and selectivity of styrene epoxidation using hydrogen peroxide showed that the selectivity of the styrene oxide reached 65% at a styrene conversion of 22% over the 1%wt catalyst.
