| titleOfInvention | Preparation method and application of nitrogen and vanadium co-doped titanium dioxide/bismuth tantalate Z-type heterojunction photocatalyst |
| abstract | The invention discloses a preparation method of a nitrogen and vanadium co-doped titanium dioxide/bismuth tantalate Z-type heterojunction photocatalyst, which comprises the following steps: slowly dropping tetrabutyl titanate into the isopropanol solution, and uniformly stirring to obtain a dispersion liquid A; adding ammonium metavanadate into absolute ethyl alcohol, and uniformly stirring to obtain a dispersion liquid B; slowly dripping the dispersion liquid B into the dispersion liquid A, uniformly stirring, heating and refluxing, and naturally cooling to room temperature to obtain a product V-TiO 2 (ii) a Subjecting the V-TiO to 2 Calcining at high temperature in ammonia atmosphere to obtain nano-block N/V-TiO 2 A photocatalyst; mixing the above N/V-TiO 2 Dispersing the photocatalyst in absolute ethyl alcohol, adding bismuth nitrate pentahydrate, adding tantalum pentachloride after the bismuth nitrate pentahydrate is completely dissolved, adjusting the pH to 9-11, and performing hydrothermal synthesis to obtain Bi 3 TaO 7 /N/V‑TiO 2 A composite material. Co-doping of TiO by N, V in the present invention 2 And Bi 3 TaO 7 The synergistic effect generated by the coupling not only improves the service life of the photo-generated electrons and the holes, but also effectively improves the stability of the catalyst after the recombination. |
