preparation example Construction

[0037] The present embodiment provides a kind of preparation method of the iron phthalocyanine composite material of graphite carbon nitride axial coordination, such as figure 1 As shown, it includes the following process: prepare iron phthalocyanine and melamine as raw materials according to the mass ratio of 1:(1-30), and mix the two evenly by ball milling; Pyrolysis at high temperature for 4-5 hours; after the pyrolysis is completed, naturally cool to room temperature, and the obtained product is the required graphite carbon nitride axially coordinated iron phthalocyanine composite material.

[0038] Among them, melamine is selected as melamine. The high-temperature pyrolysis process is completed in a tube furnace, and the inert gas atmosphere is nitrogen or helium. The ball milling and mixing process of raw materials is completed in a ball mill, and the ball milling time is not less than 1 hour.

[0039] In order to obtain a purer product, after the calcined product is c...

Embodiment 1

[0042] According to the ratio of parts by mass of 1:1, 5 g of iron phthalocyanine and 5 g of melamine were weighed; the two were fully ball-milled and mixed for 2 hours to obtain a mixed material.

[0043] Put the mixed material obtained in the above step into a tube furnace fed with nitrogen gas, and the tube furnace raises the furnace temperature to 500 °C at a heating rate of 5 °C / min; keeps the pyrolysis reaction for 4 hours, and then gradually lowers the furnace temperature After reaching room temperature, the high-temperature pyrolysis product was taken out, and the product was in the form of black powder.

[0044] Wash and dry the black product in the previous step with methanol and deionized water in sequence to remove soluble impurities therein to obtain a pure graphitic carbon nitride axially coordinated iron phthalocyanine composite material. The product in this example is named FP / CN 1 After detection, the mass fraction of iron element in the material is 7.58%.

Embodiment 2

[0046] According to the ratio of parts by mass of 1:5, 5 g of iron phthalocyanine and 25 g of melamine were weighed; the two were fully ball-milled and mixed for 2 hours to obtain a mixed material.

[0047] Put the mixed material obtained in the above step into a tube furnace fed with nitrogen gas, and the tube furnace raises the furnace temperature to 500 °C at a heating rate of 5 °C / min; keeps the pyrolysis reaction for 4 hours, and then gradually lowers the furnace temperature After reaching room temperature, the high-temperature pyrolysis product was taken out, and the product was in the form of black powder.

[0048] Wash and dry the black product in the previous step with methanol and deionized water in sequence to remove soluble impurities therein to obtain a pure graphitic carbon nitride axially coordinated iron phthalocyanine composite material. The product in this example is named FP / CN 5 After testing, the mass fraction of iron element in the material is 3.49%.

Abstract

The invention belongs to the field of environmental protection, and particularly relates to a preparation method of a graphite carbon nitride axially coordinated iron phthalocyanine composite material, an active catalyst, application of the graphite carbon nitride axially coordinated iron phthalocyanine composite material and a sewage treatment method. The preparation process of the graphite carbon nitride axially coordinated iron phthalocyanine composite material comprises the following steps: preparing iron phthalocyanine and melamine as raw materials according to a mass ratio of 1: (1-30), and carrying out ball milling on the iron phthalocyanine and the melamine to uniformly mix the iron phthalocyanine and the melamine; then carrying out high-temperature pyrolysis on the mixture for 4-5 hours at the temperature of 500-600 DEG C under the protection of an inert gas atmosphere; and after the pyrolysis is completed, naturally cooling to room temperature to obtain a product, namely the required graphite carbon nitride axially coordinated iron phthalocyanine composite material. The material can be used as a catalyst for catalytic degradation of organic pollutants by using peroxides; and the material solves the problem that the existing iron phthalocyanine catalyst has the characteristics of poor conductivity and easy aggregation in a water environment, so that the existing iron phthalocyanine catalyst is not suitable for degradation treatment of organic pollutants.

Description

technical field [0001] The invention belongs to the field of environmental protection, and specifically relates to a preparation method of an iron phthalocyanine composite material with axial coordination of graphite carbon nitride, an active catalyst, and an application of an iron phthalocyanine composite material with axial coordination of graphite carbon nitride. And a sewage treatment method. Background technique [0002] Iron phthalocyanine is a material with a phthalocyanine structure, mainly used in pigments, dyes and printing and dyeing industries. The material also has a very wide range of applications in the field of heterogeneous catalysis. However, iron phthalocyanine has poor conductivity and easy aggregation in aqueous solution, which affects the catalytic performance of the material. In addition, iron phthalocyanine is easily demetallated by some oxidants or chelating acids, so when dealing with oxidizing substances, it is easy to cause the catalytic effect ...
