specific Embodiment approach 1

[0031] Specific embodiment one: In this embodiment, an inorganic structure silicon tungsten series polyoxometalate doped ferric oxide composite nano-catalyst material is composed of polyoxometalate Co 2 co 4 (SiW 10 o 37 ) 2 and nanomaterial α-Fe 2 o 3 composition.

[0032] In this embodiment, the composite material Co is synthesized by the method of eutectic 2 co 4 (SiW 10 o 37 ) 2 / Fe 2 o 3 Synthesis, characterization and degradation of methyl orange solution. The effects of different synthesis pH conditions on polyoxometalates and composite materials were explored, and the optimal synthesis conditions of composite materials were determined. The results of photocatalytic experiments show that the composite material exhibits the best catalytic effect on the target dye when the pH is 1 and the concentration of methyl orange is 10mg / L. After the photocatalytic reaction, the degradation rate of methyl orange can reach 76.2%. . The study of its photocatalytic mecha...

Abstract

The invention discloses a silicon-tungsten polyoxometallate doped ferric oxide composite nano catalytic material with an inorganic structure as well as preparation and application thereof, and relates to a catalytic material as well as preparation and application thereof. The invention aims to solve the problem that the catalytic efficiency is low when polyoxometallate catalyzes and degrades organic matters which are difficult to degrade at present. The invention discloses synthesis and characterization of a composite material Co2Co4 (SiW10O37) 2 / Fe2O3 synthesized by a eutectic method and degradation of a methyl orange solution by the composite material Co2Co4 (SiW10O37) 2 / Fe2O3. The influence of different synthesis pH conditions on the polyoxometallate and the composite material is explored, and the optimal synthesis condition of the composite material is determined. Photocatalysis experiment results show that the composite material has the best catalysis effect on target dye when the pH is 1 and the concentration of methyl orange is 10 mg / L, and after a photocatalysis reaction, the degradation rate of methyl orange can reach 76.2%. The method is applied to the field of sewage treatment.

Description

technical field [0001] The invention relates to an inorganic structure silicon-tungsten series polyoxometalate doped ferric oxide composite nano-catalyst material and its preparation and application. Background technique [0002] As an important part of the power transmission process, substations are widely distributed in important nodes of power systems such as cities and villages. Manned substations will generate sewage during daily operation and production. The pollutants contained in sewage are generally complex, and random discharge will definitely affect the ecological environment around the substation. Therefore, proper treatment of substation sewage is one of the inevitable problems of "carbon peaking and carbon neutrality". [0003] At present, traditional methods such as sedimentation, adsorption, and filtration are mainly used for wastewater treatment. As far as substations are concerned, traditional treatment methods are clumsy, occupy a large area, have low eff...
