The prepared catalyst, [W(CO)6@DAB-MWCNT], was characterized by elemental analysis, scanning electron microscopy, and FT-IR and diffuse reflectance UV-Vis spectroscopic methods. The prepared catalyst was applied as an efficient catalyst for green epoxidation of alkenes with hydrogen peroxide in CH4CN as solvent. This heterogeneous metal carbonyl catalyst showed high stability and reusability in the epoxidation reactions without loss of its catalytic activity.واژگان کلیدی
