| Abstract:The study mainly developed the preparation of cellulose/chitosan composite aerogels loaded with visible light catalyst β-FeOOH/Fe3O4， which was subsequently used as a phototropic Fenton-like system to improve the catalytic efficiency. The degradation effect of composite aerogels on methyl orange （MO） with different β-FeOOH/Fe3O4 mass ratios and different loadings was systematically investigated， and the phototropic Fenton-like degradation mechanism was elaborated. The results showed that in phototropic Fenton-like degradation， the degradation rate of MO increased with the increase of loadings. When the mass ratio of β-FeOOH/Fe3O4 was 2∶1， the degradation ability attained the optimum state， with a degradation rate of 89.1%. The results of free radical trapping experiments showed that the main active subtances for photo-induced degradation of methyl orange could be attributed to hydroxyl radicals. |
