| titleOfInvention | The preparation method of a kind of silver oxide/silver vanadate composite photo-catalyst |
| abstract | The present invention discloses the preparation method of a kind of silver oxide/silver vanadate composite photo-catalyst, concrete steps are as follows: be under agitation that to be added drop-wise to 25 ~ 50mL concentration be in the sodium hydroxide solution of 0.1 ~ 0.2mol/L for the silver nitrate of 0.2 ~ 0.4mol/L by 25 ~ 50mL concentration, obtain silver oxide particle; By 3 ~ 5g Vn 2 on 5 powder dissolution is in the ammonia spirit of 20% ~ 25% (mass percentage concentration) in 25 ~ 30mL concentration, keeps ammoniacal liquor excessive, obtained Ammonium Vanadate Solution; Silver oxide particle is joined in Ammonium Vanadate Solution, stir 3 ~ 4 minutes, be separated rapidly, with distilled water washing 3 ~ 4 times, 105 DEG C of oven dry, i.e. obtained a kind of silver oxide/silver vanadate composite photo-catalyst.Utilize silver oxide particle as the composition of carrier and composite catalyst, utilize itself and the ammonium vanadate containing excessive ammonia to react, silver oxide particle surface portion is converted into silver vanadate and is covered in silver oxide particle surface.Silver vanadate is carried on silver oxide silver surface, and silver oxide silver close contact, is conducive to the transition of light induced electron, avoids compound, be conducive to improving catalytic efficiency. |
