| titleOfInvention | A kind of graphene oxide-based photocatalyst with visible light response and preparation method thereof |
| abstract | The invention discloses a preparation method of a graphene oxide-based photocatalyst with visible light response, comprising the following steps: S1. dissolving graphene oxide in anhydrous ethanol solution, ultrasonically treating to obtain a graphene oxide suspension, and stirring evenly , in the graphene oxide suspension, add glacial acetic acid to adjust pH, then dropwise add tetrabutyl titanate and continue to stir; S2. in the graphene oxide suspension, add mixed solution and lanthanum nitrate, and the mixed solution includes anhydrous Ethanol, glacial acetic acid, ultrapure water, and continuous stirring to obtain La-GO-TiO 2 sol; S3. La-GO-TiO 2 sol is aged to a gel state, and then dried, ground and calcined to obtain La-GO ‑TiO 2 catalyst powder. The invention uses graphene oxide, titanium dioxide and cerium ions as main raw materials, and adopts a one-step sol-gel method to combine and calcine the three; the prepared photocatalyst has good visible light photocatalytic activity, and greatly improves the absorption and utilization of visible light. |
