| titleOfInvention | Preparation method of lignin fluorescent carbon nanoparticles |
| abstract | The invention belongs to the technical field of fluorescent carbon nanoparticles, and relates to a preparation method for preparing fluorescent carbon nanoparticles by using lignin as a raw material. The preparation raw material of the fluorescent carbon nano particle has rich lignin sources, is the second most abundant and renewable organic matter in the world, and is second to cellulose. The invention not only can make high-value utilization of lignin resources, but also greatly simplifies the preparation method of the fluorescent carbon nano particles. The inherent benzene ring structure of the lignin meets the requirement of a conjugated system, and exciting light can be absorbed without the processes of dehydration, carbonization and aromatization of carbohydrate, and certain fluorescence is released, so that the preparation process of the fluorescent carbon nano particles is greatly simplified. The preparation method of the lignin fluorescent carbon nano particle comprises the following steps: refining lignin to reduce impurity interference; dissolving and dispersing refined lignin by using a solvent; and (3) separating the lignin solution by using a centrifugation or dialysis method to obtain the lignin fluorescent carbon nano particle solution. |
