Embodiment 1

[0039] Weigh a Fe / S mixture with a total mass of 500 mg (the molar ratio of Fe and S is 1:1).

[0040] Weigh 240 mg of PAN and grind it into a finer powder.

[0041] Add the weighed Fe / S mixture into the ground PAN powder, grind again until the mixture is uniform, and vacuum seal the tube after tableting with a tablet machine. Put the sealed tube sample into a muffle furnace, slowly heat to 600-1000°C and react for 24-72 hours. After the reaction, the quartz tube was opened to take out the product, and ground to obtain the solid-phase reaction product FeS / CPAN.

Embodiment 2

[0043] A mixture of Fe, Se and S with a total mass of 500 mg (the molar ratio of Fe, Se and S is 2:1:1) was placed in an agate mortar, and 240 mg of PAN after grinding was weighed, mixed and Grind evenly, then use a tablet press to compress into tablets, and then vacuum seal in a quartz tube. Put the sealed quartz tube into the muffle furnace, heat slowly to 600-1000°C and react for 24-72 hours. After the reaction, open the quartz tube to take out the product, grind it, and obtain the solid phase reaction product Fe 2 SSe / CPAN.

Embodiment 3

[0045] Weigh the Fe / Si / S mixture with a total mass of 500 mg (the molar ratio of Fe, Si, and S is 2:1:4).

[0046] Weigh 240 mg of PAN and grind it into a finer powder.

[0047]Add the weighed Fe / Si / S mixture into the ground PAN powder, grind it until it is evenly mixed, vacuum seal it into a quartz tube after tableting and transfer it to a muffle furnace, heat slowly to 600-1000°C and react for 24 ~72 hours. After the reaction, open the quartz tube to take out the product, grind it well, and obtain the solid phase reaction product Fe 2 SiS 4 XRD of / CPAN.

Abstract

The invention relates to a preparing method of a transition metal sulfide / carbonized polyacrylonitrile composite material, and belongs to the technical field of material preparation. The preparing method includes the steps that transition metal, sulfur and polyacrylonitrile are mixed and pressed into sheets, and the sheet-like mixture is sealed in the quartz tube in vacuum and reacts for 24-72 h at the environment temperature of 600-1000 DEG C to obtain the transition metal sulfide / carbonized polyacrylonitrile composite material. The carbon material can be obtained while transition metal sulfide is synthesized, which is beneficial for tightly combining the transition metal sulfide and the carbon material, and the related performance in the application field is improved. In addition, the preparing method is simple, easy to operate and suitable for large-batch production, and the requirement for equipment is closer to industrial application needs.

Description

technical field [0001] The invention belongs to the technical field of material preparation, in particular to a preparation method of a transition metal sulfide / carbonized polyacrylonitrile (CPAN) composite material. Background technique [0002] As a member of the family of inorganic materials, transition metal sulfides have attracted extensive attention and research because of their special electrical, optical, catalytic and mechanical properties. Especially in the field of energy storage, transition metal sulfides have been used as electrode materials for supercapacitors and lithium-ion batteries. However, most transition metal dichalcogenides are semiconductors with narrow band gaps, and their applications in the field of energy storage are greatly limited. Therefore, by compounding transition metal sulfides with carbon materials, their electrical conductivity can be increased. In addition, the special skeleton structure of carbon materials can effectively buffer the v...
