According to the American physicist organizational networks, June 21 (Beijing time) reported that the U.S. Northern Illinois University scientists in the June issue of "Materials Chemistry" magazine published a paper that they had found a large-scale production of graphene Simple Methods: combustion in dry ice pure metallic magnesium way the carbon dioxide can be directly converted into multi-graphene (less than 10 atoms).

 

Graphene is a two-dimensional carbon material, which is the thinnest kind of known materials with unique electronic and mechanical properties, application prospect is extremely broad, is considered the most likely to replace silicon in electronic materials.

 

Responsible for the study of Northern Illinois University professor of chemistry and biochemistry Narayan Othman said: "The long was found burning magnesium metal in carbon dioxide produces carbon, but before us, and no scientists report or confirm this kinds of carbon is mainly constituted by a multi-layer graphene. "This synthetic process has produced a large number of multi-layered graphene's potential. Although there are many ways to prepare graphene, but many require the use of hazardous chemicals, technology is also more cumbersome. In contrast, the new method is simple, environmentally friendly and cost.

 

Osman said his research team originally thought this way the production of single-walled carbon nanotubes, but eventually serendipitously to isolate the multilayer graphene, which makes them feel very surprised.

 

First author, Northern Illinois University researcher Amartya Chakrabarti said, this is a very simple technique, scientists had also conducted a similar attempt, but no one really carefully examined these carbon structures .

 

Inventor of graphene, was also awarded the Nobel Prize and the Nobel Prize funny. Sticky tape on graphite under a thin layer, in the accustomed tedious process new materials and high-precision equipment manufacturers who seems incredibly simple. Today, scientists have found that to unlimited potential for mass production of this new material, is equally simple. Burning magnesium in carbon dioxide is used to prove a flammable magnesium, giving students demonstration experiments. Who would have thought high school experiment bottle, it can be born the forefront of the industry structure of matter? Graphene is indeed a simple and interesting material in the future it might make our cell phones, computers and the battery becomes easy and fun.
