토글The use of carbon in the field of energy
Carbon in fossil fuel
In fossil fuels is one of the most important forms of carbon in the field of energy. Coal, oil and gas are common sources of energy in our daily lives. They contain a lot of carbon. Coal, for example, is mainly formed by the long geological processes of ancient plant remains, with high carbon content. When coal burns, carbon and oxygen react to release a lot of heat energy for power generation, heating, etc.. It is a more traditional use of carbon in the field of energy. However, this combustion mode also produces a large amount of carbon dioxide and other temperature chamber gases. These have a certain impact on the environment.
- New carbon energy materials
With the development of science and technology, new carbon energy materials are gradually emerging. For example, materials such as carbon nanotubes have great application potential in the field of batteries. They can improve the performance of the battery, increase the conductivity and stability of the battery. And thus improve the energy storage efficiency of the battery. It is of great significance for the new energy vehicles and renewable energy storage and other aspects. And it is an innovative use of carbon in the field of modern energy.

Carbon black materials
Carbon black materials are indispensable in modern industry. In the rubber industry, carbon black is an important reinforcing agent. After the addition of carbon black rubber products, such as tires, its wear resistance, tear resistance and strength have been greatly improved. And it can adapt to a variety of complex road conditions and driving conditions. In ink manufacturing, carbon black is used as a pigment to give the ink good blackness and hiding power. This ensures the bright color and clear image of the printed matter.

Carbon brush
Carbon brushes play a key role in electrical equipment. In the motor, the carbon brush is responsible for passing the external electrical flow to the rotor windings. So the motor can operate normally. The carbon brush has good electrical conductivity and self-lubrication. So in the process of high-speed friction with the commutator, it can ensure the stable transmission of current. And it can also reduce wear, and extend the service life of the motor. It is widely used in many electrical equipment such as power tools, industrial motors and generators.
The use of carbon in chemistry
Carbon in organic synthesis
In organic chemical synthesis, carbon is the core element. Many organic compounds cannot be synthesized without carbon. For example, through the formation of carbon-carbon bonds, a variety of complex organic molecules can be synthesized. Such as drugs, fragrances, plastics, etc.. Many common plastics, such as polyethylene, polypropylene, etc., are carbon-based polymer compounds. And these plastics are widely used in daily life, from packaging materials to household items.
- Activated carbon materials
Activated carbon is a carbon material with highly developed pore structure. And its specific surface area is very large. In the chemical industry, activated carbon is mainly used for adsorption and separation. For example, in the water treatment process, activated carbon can absorb harmful substances in the water, thereby purifying the water quality. In terms of air purification, activated carbon can also adsorb harmful gases such as formaldehyde, benzene, etc.. It provides people with a healthy indoor environment. This is one of the important uses of carbon in daily life.
In the field of medicine
Biocarbon material
Biocarbon material has good biocompatibility, and has been widely used in tissue engineering and other fields. For example, biocarbon materials can be used as scaffold materials to help cells grow and repair tissue. It can simulate the microenvironment of human tissue, promote the regeneration of damaged tissue. And it can provide new ideas and methods for medical treatment.
- Carbon-based drug carrier
Carbon nanomaterials can also be used as drug carriers. Because of its unique physical and chemical properties, it can effectively load drugs and achieve drug targeted delivery. This helps improve the therapeutic effect of drugs, reduce the side effects of drugs on normal tissues. And it has great potential in the treatment of diseases such as cancer.
The use of carbon in other fields
In agriculture
In agriculture, the role of carbon is not to be underestimated. For example, organic fertilizers are rich in carbon. This can improve soil structure, increase soil fertility, and promote the growth of crops. In addition, carbon dioxide can be used as gas fertilizer at a certain concentration to improve the efficiency of plant photosynthesis. Thereby increasing the yield of crops.
In art and culture
From ancient charcoal paintings to modern carbon black pigments, carbon has a long history in art and culture. Charcoal is a common tool for painting, which can produce rich lines and tones. Carbon black is widely used in ink, paint and other fields to add color and texture to artwork and prints.
Uses of carbon in daily life
In daily life, carbon is incorporated into a variety of good things, such as fishing rods and toner. Carbon fiber fishing rods are favored by fishing friends. The traditional fishing rod is often heavy, easy to fold and other short board. It is overcome by carbon fiber. Its light weight, fishing friends hold for a long time not tired. High strength, can easily cope with big fish pulling. Good elasticity, sensitive signal transmission when the fish bite the hook, powerful buffer, reduce running fish, make fishing more enjoyable.
Toner plays an important role in the office printing scene. In laser printers and copiers, the toner particles are fine and uniform. And the electrical conductivity and absorption are good. When working, the static electricity is adsorbed on the sensitive drum, imaging according to the signal. And then transfer the paper and heat fixing, so that the text image is clearly presented. Students printing materials, office documents processing professionals, etc., are inseparable from the toner. It ensures the smooth paper information, is the daily office learning assistant.
The uses of various allotropes of carbon
