Embodiment 1

[0027] (1) Disperse 0.05g of ferric oxychloride and 0.5mL of aniline into 20mL of acetonitrile, and react at 90°C for 12h to obtain solvothermal product A;

[0028] (2) The solvothermal product A was washed three times with ethanol, and then dried at 80° C. for 12 hours to obtain product B;

[0029] (3) The product B was calcined under a nitrogen atmosphere, that is, the temperature was raised to 700° C. at a heating rate of 5° C. / min, and then kept for 4 hours to form a finished porous carbon intercalation-coated iron oxide nanoplate.

[0030] Depend on figure 1 It can be seen that the disappearance of ferric oxychloride (010) peak (11.05 o ) and a new characteristic peak (12.5 o ), indicating that aniline in the product B is successfully intercalated into the ferric oxychloride interlayer;

[0031] Depend on figure 2 It can be seen that the calcined product is nitrogen-doped carbon-coated iron oxide, and the crystal form of nitrogen-doped carbon is an amorphous structur...

Embodiment 2

[0035] As described in Example 1, the difference is that 0.5g of diphenylamine is added and reacted in ethanol at 120°C for 20h. During calcination, the product B is heated to 900°C at 2°C / min under a nitrogen atmosphere for 5h and then porous carbon intercalation Coated iron oxide nano plate material. The finished product prepared in this embodiment can completely degrade rhodamine B within 60 minutes.

Embodiment 3

[0037] As described in Example 1, the difference is that 1.0 mL of dimethylaniline is added and reacted in ethanol at 180°C for 10 hours. During calcination, the product B is heated to 850°C at 10°C / min under a nitrogen atmosphere for 4 hours, and then porous carbon is obtained. Intercalation coated iron oxide nano plate material. The finished product prepared in this embodiment can degrade 98% rhodamine B within 60 minutes.

Abstract

The invention belongs to the technical field of inorganic nano material preparation, and in particular relates to a porous nitrogen-doped carbon intercalated coated ferric oxide nano panel material and a preparation method thereof. Coating layers are arranged between layers of the ferric oxide nano plate of the layered structure and on the surface of the nano plate. The coating layers are nitrogen-doped carbon of a porous structure, so that the tight contact of organic carbon and ferric oxide is enhanced, the synergistic effect of the two is exerted to the maximum extent, and the photoelectricproperty is improved and the application range is wide. The invention also provides a preparation method thereof. By taking chloride ferric oxide and organic amine compounds as raw materials which are low in price, rich in reserve and environment-friendly and employing a process of intercalating reaction and calcining, the material is simple, easy to operate, controllable in component, low in cost and suitable for scaled production.

Description

technical field [0001] The invention belongs to the technical field of preparation of inorganic nanometer materials, and in particular relates to a porous nitrogen-doped carbon intercalation-coated iron oxide nanoplate material and a preparation method thereof. Background technique [0002] The rapid development of today's social economy has brought about environmental pollution and energy depletion, which have seriously threatened human survival and health. It is imminent to develop novel materials to deal with energy crisis and environmental pollution, and to realize the sustainable development of human beings. Composite materials can effectively avoid the limitations of a single material and maximize the performance of materials, so they have attracted much attention. In particular, iron oxide-based materials have great advantages in dealing with environmental pollution and solving energy crises due to their abundant reserves, low price, and environmental friendliness. ...
