| titleOfInvention | A kind of bismuth vanadate/silver chromate heterojunction photocatalyst and preparation method and application thereof |
| abstract | The invention discloses a bismuth vanadate/silver chromate heterojunction photocatalyst and a preparation method and application thereof: the heterojunction photocatalyst consists of BiVO 4 and nano-Ag 2 selectively deposited on the BiVO 4 (040) crystal plane CrO 4 is assembled, the BiVO 4 has a quadrangular bipyramid microstructure with cut corners, and the mass of BiVO 4 accounts for 70-80% of the total mass of the heterojunction photocatalyst; including the following steps: S1: hydrothermal method Preparation of bismuth vanadate; S2: Preparation of heterojunction photocatalyst: Add BiVO 4 into distilled water, after ultrasonic dispersion, under the condition of magnetic stirring, add a certain amount of AgNO 3 solution, and then slowly add a certain amount of K 2 dropwise CrO 4 solution, a brick-red precipitate was formed, and the reaction was continuously stirred for 1-2 h, then the precipitate was left to stand for 12-24 h, centrifuged, washed with water for 6 times, and vacuum-dried. Compared with the traditional deposition method, the heterojunction formed by the selective adsorption deposition method of the present invention has better stability, higher interface bonding degree and higher visible light catalytic activity. |
