| titleOfInvention | TiO 22Preparation method of/ZnO semiconductor heterojunction SERS active substrate |
| abstract | TiO 2 2 ZnO semiconductor hetero-junctionA preparation method of a mass-junction SERS active substrate relates to a preparation method of a SERS active substrate. It is to solve the existing TiO 2 The preparation method of the/ZnO semiconductor heterojunction is complex, and the activity is low when the ZnO semiconductor heterojunction is used as an SERS substrate. The method comprises the following steps: dripping tetrabutyl titanate solution into mixed solution of ethanol, water and concentrated nitric acid to prepare sol, and then carrying out hydrothermal treatment and roasting to obtain TiO 2 Nanoparticles; adding TiO into the mixture 2 Nanoparticles added to Zn (NO) 3 ) 2 .6H 2 Adding NaOH aqueous solution and an accelerant into the O aqueous solution, stirring, settling, drying and roasting to obtain TiO 2 A novel SERS active substrate of a ZnO semiconductor heterojunction. The lowest detection concentration of the compound on 4-mercaptopyridine reaches 1 x 10 ‑9 And M, the method can be used in the field of surface enhanced Raman detection. |
