Efficient oxidation of cinnamon oil to natural benzaldehyde over β-cyclodextrin-functionalized MWCNTs

β-cyclodextrin (β-CD) functionalized MWNTs (MWCNTs-g-CD) were designed for the oxidation of cinnamon oil to natural benzaldehyde in the aqueous solutions. The synergistic effect between MWCNTs and β-CD leads to the remarkably enhanced performance of MWCNTs-g-CD for the catalytic oxidation of cinnamaldehyde.
