ABSTRACT Iron(III) bis(phenol) amine complex immobilized on the surface of functionalized graphene oxide nanosheets (FeL GDC ‐AP/GO) has introduced as a highly active and recoverable catalyst for epoxidation alkenes. Optimizing different parameters in oxidation styrene model substrate revealed that 100% conversion selectivity were obtained toward presence H 2 O (28 wt%) oxidant water/acetone (3:1) solvent system bicarbonate buffer system. Furthermore, displayed 54%–100% 90%–100% various aromatic aliphatic alkenes under optimized reaction conditions at room temperature. The recycling experiment showed FeL ‐AP/GO could be easily recovered by simple filtration recycled six times without loss activity selectivity. high catalytic developed attributed to well‐designed coordination sphere around iron core well GO support, which facilitates electron transfer process beside recovery.
