Abstract

The invention discloses a graphene oxide-terbium oxide-ferric oxide composite material, a synthetic method and application thereof in catalytic degradation. The graphene oxide-terbium oxide-ferric oxide composite material is prepared by combining a direct precipitation method and a solvothermal method. The composite material is characterized by a Fourier transform infrared spectrum, a scanning electron microscope and an X-ray diffraction spectrometer, and structures and properties thereof are researched, then a malachite green aqueous solution is catalytically degraded under the combined action of potassium peroxydisulfate serving as an oxidant, and the catalytic degradation capacity of the catalyst on organic dye malachite green under the conditions of different concentrations, differentpH values, different temperatures and different catalyst usage amounts is respectively researched. The method is simple in synthesis process, mild in condition and high in experimental result reproducibility, and a product with stable performance can be obtained.

Description

【Technical field】 [0001] The invention belongs to the technical field of catalyst synthesis, and in particular relates to a graphene oxide-terbium oxide-iron oxide composite material, a synthesis method and its application in catalytic degradation. 【Background technique】 [0002] There are many wastewater treatment technologies, and the traditional treatment methods mainly include: physical methods include adsorption method, membrane separation method, and ion exchange method. Biological treatment methods include: white rot bacteria removal method, microbial adsorption method, and anaerobic bacteria decomposition method. Chemical methods include: chemical oxidation, Fenton oxidation, ozone oxidation, photocatalytic oxidation, electrochemical degradation, sodium hypochlorite oxidation. Photocatalytic oxidation is a relatively common method for treating sewage. These methods still need to be further improved due to reasons such as large investment, high cost, and low process...
