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.
