| titleOfInvention | BiOI/Bi/TiO of ternary heterostructure2Composite photocatalytic material and preparation and application thereof |
| abstract | The invention relates to a BiOI/Bi/TiO of a ternary heterostructure 2 Composite photocatalytic material, TiO 2 In order to expose the nano-sheet structure of the {001} crystal face and the {101} crystal face at the same time, oxygen vacancy and unsaturated Ti exist on the surface 3+ A defect site; the particle size of the BiOI is about 50-200 nm, and the BiOI is uniformly dispersed in the TiO 2 {001} crystal face; sandwiching metallic Bi particles between BiOI and TiO 2 Interface between the contacts. The preparation method comprises the following steps: firstly, preparing a crystal face which simultaneously exposes {001} and {101} crystal faces, and the surface of the crystal face has oxygen vacancy and unsaturated Ti 3+ TiO of defect sites 2 Nanosheets; then adding TiO 2 Adding the nanosheets and the bismuth source into the dispersed organic solution, dripping the organic solution containing the iodine source under vigorous stirring, and continuing stirring; transferring the mixture into a stainless steel high-pressure reaction kettle, and reacting for 12-36 h at the temperature of 140-170 ℃; cooling to room temperature, filtering, washing and vacuum drying. According to the invention, by TiO 2 The strong interaction between the metal Bi and the BiOI enhances the dispersibility of the BiOI, and the metal Bi is formed in situ between contact interfaces, so that the photon yield can be improved, and photo-generated electrons and holes have stronger redox capability and better catalytic activity. |
