Cucurbit[7]uril promoted Fenton oxidation by modulating the redox property of catalysts

Abstract

The redox property of a ferrocene derivative, the catalyst of Fenton oxidation, is modulated by the host–guest complexation of cucurbit[7]uril. The supramolecularly modulated catalyst significantly accelerates the catalytic oxidation of dye chromophores, thus providing a way to avoid product inhibition and broadening the range of substrates.
