A wool supported manganesedioxide nano-scale dispersion (MnO2@wool) was synthesized by soaking wool in a potassium permanganate solution and characterized by X-ray diffraction (XRD), thermogravimetric analysis (TGA), and scanning electron microscopy (SEM). The synthesized catalyst, MnO2@wool complex, has been found to be able to catalyze the selective aerobic oxidation of alkyl arenes, alcohols, oximes
