| titleOfInvention | A kind of preparation of sulfur/nitrogen/phosphorus co-doped titanium dioxide photocatalyst and its application |
| abstract | A preparation of sulfur/nitrogen/phosphorus co-doped titanium dioxide photocatalyst and application thereof. The invention relates to a sulfur/nitrogen/phosphorus co-doping photocatalyst. Using butyl titanate, thiourea, urea and phosphoric acid as precursors, a S/N/P- TiO2 photocatalyst is prepared by a sol-gel method. , the prepared material is anatase phase, in which S exists in the form of S 4+ and S 6+ on the surface of the lattice, and the incorporation of S widens the forbidden band of titanium dioxide and improves the photocatalytic performance of the material; N After the element is doped into the lattice, Ti-N bonds are formed, which can red-shift the light absorption range of TiO 2 ; while P replaces Ti 4+ in the Ti-O-Ti lattice in the near-surface region with P 5+ , forming a P‑O‑Ti bond, thereby shifting the binding energy of Ti 2p to a lower position. The invention uses K. mikielii as the test algae to test the algae removal performance of the material, and the results show that the prepared material S/N/P-TiO 2 photocatalyst successfully inhibits the growth of algal cells and has a good algae removal effect. |
