| titleOfInvention | Method for preparing carbon quantum dots by cutting graphite oxide based on strong base, product and application thereof |
| abstract | The invention discloses a method for preparing carbon quantum dots by cutting graphite oxide based on strong alkali, a product and application thereof, and aims to solve the problems that materials such as graphite and the like are often required to be oxidized for a long time in a strong corrosive medium in the existing chemical cutting method for preparing the carbon quantum dots, the operation conditions are dangerous, the heat release is serious, the amplification is not easy, and the application of the carbon quantum dots prepared by the method is limited. According to the method, the graphene oxide is cut at high temperature by using potassium hydroxide and oxygen to obtain the carbon quantum dots with high carboxyl content, and the carbon quantum dots do not need to be oxidized in a corrosive medium for a long time, so that the risk of an experimental technology is reduced, the mass production is easier to realize, and the method shows wider application potential. The invention provides a method for preparing a novel carbon quantum dot by etching graphene oxide with strong base, and the method is applied to trace detection of uranyl ions and has high application value and good application prospect. |
