Abstract
Mesoporous materials such as manganese dioxide (MnO2) nanoflower present infinite application prospects for dye degradation. To solve the problem of difficult recovery of catalyst, a novel MnO2@cellulose composite film was fabricated through a low temperature route. This film possessed mechanical strength and could buckle flexibly. According to scanning electron microscopy, the microstructure of the composite film was a three-dimensional porous frame structure in which MnO2 particles are uniformly distributed. In addition, X-ray diffraction, X-ray photoelectron spectroscopy, Fourier-transform infrared spectroscopy, and thermogravimetric analyzer were used to investigate the structural information of the film. Finally, the MnO2@cellulose film showed better removal rate than pure cellulose film (the removal rate can reach to 76.1% after 90 min) and a high recycle stability. Most importantly, it is worth mentioning that the composite film has successfully solved the problem of difficult recovery of catalyst and laid a good foundation for the commercial application of MnO2 in the catalysis field.
