Embodiment 1

[0039] (1) Mix 30ml of aniline and 0.17g of hexachlorocyclotriphosphazene, carry out a closed reaction for 5h at a reaction pressure of 2MPa and a reaction temperature of 200°C, then release the pressure to normal pressure, and distill off excess aniline from the reaction to obtain solid matter;

[0040] (2) Under the protection of inert gas nitrogen, the solid material obtained in step (1) was subjected to a high temperature treatment at 900° C. for 2 hours to obtain the sheet-like nitrogen-phosphorus co-doped porous carbon material, which was named C1.

Embodiment 2～7

[0041] Embodiment 2~7: the investigation of temperature of reaction in the step (1)

[0042]Except that the reaction temperature in step (1) is replaced by 180°C, 220°C, 160°C, 240°C, 140°C, 260°C respectively, other operations are all the same, thus carrying out Examples 2 to 7 in sequence, respectively Named as C2 ~ C7.

Embodiment 8～10

[0043] Embodiment 8~10: the investigation of high temperature treatment temperature in step (2)

[0044] Except that the high-temperature treatment temperature in step (2) was replaced by 800° C., 900° C., and 1000° C., other operations were unchanged, so that Examples C8 to C10 were carried out in sequence.

Abstract

The invention provides a flake-shaped nitrogen and phosphorus co-doped porous carbon material. The flake-shaped nitrogen and phosphorus co-doped porous carbon material is prepared by the following method: mixing aniline and phosphonitrilic chloride trimer and sealing and reacting for 2h to 24h under the conditions that the pressure is 1MPa to 10MPa and the temperature is 140 DEG C to 260 DEG C; then releasing pressure to normal pressure and drying by distillation to obtain a solid substance; under the protection of inert gas, carrying out high-temperature treatment on the solid substance at 400 DEG C to 1000 DEG C for 1h to 6h, so as to obtain a finished product. The flake-shaped nitrogen and phosphorus co-doped porous carbon material provided by the invention has excellent electric properties and can be used for preparing a capacitor electrode, especially a super-capacitor electrode, so that the material can be used for a capacitor, especially a super-capacitor, and has extremely great application potential and industrial value in the field of energy storage.

Description

[0001] (1) Technical field [0002] The invention provides a sheet-like nitrogen-phosphorus co-doped porous carbon material that can be used for supercapacitors, a preparation method and application thereof, and belongs to the field of inorganic functional materials. [0003] (2) Background technology [0004] Energy is an important material basis that supports people's lives and social and economic development. Since the beginning of the 21st century, on the one hand, with the large-scale use of fossil energy, traditional energy has become increasingly depleted; There is a serious contradiction between people's increasing energy demands. Therefore, the storage and conversion of energy is undoubtedly one of the major challenges facing people in the 21st century. Supercapacitor is a kind of power energy storage device, which has the ability of fast charging and discharging. Compared with traditional capacitors, it has high power density and energy density. It has broad applica...
