| titleOfInvention | Preparation method of niobium-doped bismuth tungstate photocatalytic material |
| abstract | The invention relates to the field of semiconductor materials, and aims to provide a preparation method of a niobium-doped bismuth tungstate photocatalytic material. The method comprises the following steps: dissolving bismuth salt in oxalic acid aqueous solution, and dropwise adding tungstic acid aqueous solution into the oxalic acid aqueous solution of bismuth salt under stirring; then adding the milled niobium oxide powder, and adjusting the pH value of the mixture to be neutral by using ammonia water; continuously stirring after ultrasonic dispersion treatment under a closed condition to obtain uniform precursor suspension; putting the mixture into a reaction kettle for hydrothermal reaction, and naturally cooling the mixture to room temperature after the reaction is finished; and centrifuging the obtained mixture to obtain a precipitate product, washing and drying to obtain the niobium-doped bismuth tungstate photocatalytic material. The method does not use any template agent and surfactant, overcomes the defect of a single bismuth tungstate material through the synergistic effect of nano effect and element doping, obviously improves the migration and separation capability of bismuth tungstate photon-generated carriers, widens the absorption spectrum range of bismuth tungstate, and improves the utilization efficiency of solar energy. |
