| titleOfInvention | A kind of preparation method of WO3/graphene quantum dot composite film photoanode |
| abstract | The invention provides a preparation method of WO 3 /GQDs composite photoanode, which solves the problem of low photoelectric conversion efficiency of WO 3 . In the invention, a tungsten sheet is used as a matrix, an aqueous solution of sodium fluoride and sodium sulfate containing graphene quantum dots is used as an electrolyte, and a porous tungsten trioxide composite film containing graphene quantum dots (GQDs) is prepared by a pulse anodic oxidation method. The composite film is heated to 300-700° C. in a nitrogen tube furnace and kept for 3 hours, which is beneficial to improve the crystallinity of the WO 3 /GQDs composite film. Compared with the pure WO 3 thin film samples, the photocurrent of the GQDs/WO 3 composite film was significantly increased and the cycle life was very good. The method of the invention is simple and easy to operate, and the prepared GQDs/WO 3 composite film has high photocatalytic activity and stability. |
