Cobalt(II) Schiff base complex on multi-wall carbon nanotubes (MWNTs) by covalently grafted method: Synthesis, characterization and liquid phase epoxidation of cyclohexene by air

► [Co(OH)2-salophen] complex was covalently grafted on the MWNTs. ► The catalytic activity was tested in the epoxidation of cyclohexene. ► Nanocomposites indicate good catalytic activity and selectivity in the epoxidation.
