| titleOfInvention | A preparation method of nitrogen-sulfur-doped fluorescent carbon nanosheets and its application in detecting dichromate ions |
| abstract | The invention discloses a preparation method of a nitrogen-sulfur-doped fluorescent carbon nanosheet and an application thereof for detecting dichromate ions, belonging to the technical field of fluorescence sensing. Using trisodium citrate and 6-mercaptopurine as raw materials, N,N-dimethylformamide and water as solvents, nitrogen-sulfur-doped fluorescent carbon nanosheets were prepared by a one-step solvothermal method. The method for preparing fluorescent carbon nanosheets of the present invention has the advantages of simple operation, low cost, and easy large-scale production, and the prepared fluorescent carbon nanosheets have high fluorescence properties, good photostability, adjustable emission spectrum and easy functionalization of the surface Etc. When Cr 2 O 7 2‑ exists in the solution, new substances can be generated with carbon nanosheets, resulting in static quenching of fluorescence. Based on this, a rapid and sensitive method for the detection of Cr 2 O 7 2‑ was established. |
