|| Charcoal ash
||carbon ash can be extracted with toluene to obtain more than 13% fullerenes. The general composition of the extract is 75% C60, 22% C70 and other high fullerenes.
Fullerene is a carbon allotrope. Any substance that consists of a single element of carbon and exists in a spherical, oval, or tubular structure can be called a fullerene. Fullerene has a similar structure to graphite, but graphite has only six-membered rings, while fullerenes may have five-membered rings. In 1985 Robert Curl et al. Produced C 60 . In 1989, experiments by German scientists Huffman and Kraetschmer confirmed the cage structure of C 60. Since then, fullerenes discovered by physicists have been pushed to a new stage of research by the scientific community. The structure of fullerene is similar to that of the architect Fuller, so it is called fullerene.
As a prominent representative of the fullerene family, the C 60 molecule is a spherical 32-hedron composed of 60 carbon atoms connected by 20 six-membered rings and 12 five-membered rings, which is very close to the structure of a football. Its unique structure and singular properties Has attracted the attention of scientists from various countries. So far, C 60 research has involved many disciplines and applied research fields such as energy, lasers, superconductors and ferromagnets, life sciences, materials science, polymer science, catalysis, etc., and has increasingly shown great potential and important Research value and application value.
Fullerene and its application
Fullerene has been widely used in daily cosmetics due to its excellent properties (or functions) such as free radical capture, light absorption, superconducting semiconductor, perfect structure, DNA affinity, electron acceptor, efficient adsorption, and embedded molecules. , Pharmaceutical intermediates, health products, rubber / film material modifiers, high-tech energy sources, composite material additives and many other fields.
