| titleOfInvention | Immobilized F, N, Ag co-doped titanium dioxide photocatalyst and preparation method and application thereof |
| abstract | The invention belongs to the field of photocatalytic materials, and discloses an immobilized F, N, Ag co-doped titanium dioxide photocatalyst as well as a preparation method and application thereof. The preparation method of the photocatalyst comprises the following steps: (1) soaking the photocatalyst carrier in an acid solution, taking out, cleaning, drying and calcining for later use; (2) uniformly mixing a titanium dioxide precursor and absolute ethyl alcohol, dropwise adding a hydrolysis inhibitor under a stirring state, and then adding an ammonium fluoride solution and a silver nitrate solution to obtain a mixed solution; (3) and (3) immersing the photocatalyst carrier calcined at high temperature in the step (1) into the mixed solution obtained in the step (2), then transferring the photocatalyst carrier into a hydrothermal reaction kettle for reaction, taking out the photocatalyst carrier in the hydrothermal reaction kettle after the reaction is finished, washing and drying to obtain the immobilized photocatalyst. Compared with pure titanium dioxide, the obtained catalyst has obviously enhanced photocatalytic performance, firm solid-carrying of the catalyst and difficult shedding; the preparation process is simple and has good repeatability. |
