| titleOfInvention | Photocatalyst and preparation method and application thereof |
| abstract | The invention discloses a photocatalyst and a preparation method and application thereof, wherein the method comprises the following steps: and mixing the graphene oxide solution and the strontium titanate precursor to obtain a mixed solution, adding the Cd precursor into the mixed solution, heating, and gradually adding the S precursor in the heating process to obtain the strontium titanate, graphene and CdS compounded ternary composite photocatalyst. According to the invention, the ternary composite material is adopted, so that the electron transmission capability of graphene and the heterostructure of CdS and strontium titanate exist in the same material at the same time, and compared with a binary structure, the photocatalytic performance is greatly improved; according to the preparation method, no reducing agent is used, and the brown graphene oxide is reduced to black reduced graphene under the hydrothermal condition; according to the invention, a one-pot method is adopted to prepare the ternary structure, and the precursors of strontium titanate and CdS and graphene oxide are uniformly mixed and then placed in a reaction kettle to complete one-step reaction, so that the time and energy are saved. |
