A kind of preparation method and application of BiOI-Bi5O7I-Bi three-phase composite material |
| abstract |
The invention belongs to the technical field of photocatalysts, and in particular relates to a preparation method and application of a BiOI-Bi 5 O 7 I-Bi three-phase composite material, and aims to provide a three-phase composite photomaterial with higher photocatalytic activity. A preparation method of a three-phase composite material of the present invention comprises: 1) dissolving a certain amount of bismuth nitrate in water to obtain a white suspension; then dissolving a certain amount of potassium iodide in the white suspension to obtain a red color suspension; add a certain amount of sodium borohydride to the red suspension, fully react to obtain a reddish-brown suspension; 2) adjust the reddish-brown suspension to pH=6-7 with sodium hydroxide, then transfer to high pressure The hydrothermal reaction is carried out in the reactor; 3) the suspension after the complete hydrothermal reaction is naturally cooled to normal temperature, centrifuged, and the precipitate is washed and dried to obtain the final product. The invention also relates to the use of the three-phase complex. The three-phase complex prepared by the method of the invention can efficiently degrade organic pollutants. |
