A nanotube catalyst efficient and reusable for epoxidation
In the present work, the preparation, characterization and investigation of catalytic activity of tungsten hexacarbonyl, W(CO)8, supported on multi-wall carbon nanotubes modified with 1-aminopyridine is reported. The catalyst, [W(CO)5@Apy-MWCNT], was characterized by physico-chemical and 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….
