Embodiment example 1
[0028] The invention discloses a silver ferrite / silver vanadate p-n heterojunction composite photocatalyst. The silver ferrite / silver vanadate p-n heterojunction composite photocatalyst uses silver vanadate as a carrier and uses silver ferrite to modify the silver vanadate.
[0029] In this embodiment, the silver ferrite / silver vanadate composite photocatalyst has a mass percentage of 1 wt% of silver ferrite in silver vanadate.
[0030] In this embodiment, the silver ferrite is a nano particle, which is a p-type semiconductor, and the silver vanadate is a micron particle, which is an n-type semiconductor.
[0031] The preparation method of described silver ferrite / silver vanadate composite photocatalyst comprises the following steps:
[0032] Weigh 0.808 g of ferric nitrate and 0.340 g of silver nitrate in 50 mL of ultrapure water, stir in the dark for 10 min, add 10 mL of 60 g / L NaOH solution to the solution, continue stirring for 30 min, pour the solution into Put it into a...
Embodiment example 2
[0039]A silver ferrite / silver vanadate composite photocatalyst, which is basically the same as the implementation case 1, the only difference is that in the silver ferrite / silver vanadate composite photocatalyst of the implementation case 2, the mass percentage of silver ferrite to silver vanadate is 2 %.
[0040] A preparation method of the silver ferrite / silver vanadate composite photocatalyst of the above-mentioned embodiment is basically the same as the preparation method of Example 1, the only difference being that the mass of silver ferrite used in Example 2 is 0.0038 g.
[0041] The silver ferrite / silver vanadate composite photocatalyst prepared in Example 2 was named 2 wt% AFO / AVO.
Embodiment example 3
[0043] A silver ferrite / silver vanadate composite photocatalyst, which is basically the same as the implementation case 1, the only difference is that in the silver ferrite / silver vanadate composite photocatalyst of the implementation case 3, the mass percentage of silver ferrite to silver vanadate is 3 %.
[0044] A preparation method of the silver ferrite / silver vanadate composite photocatalyst of the above-mentioned embodiment is basically the same as the preparation method of Example 1, the only difference being that the mass of silver ferrite used in Example 3 is 0.0057 g.
[0045] The silver ferrite / silver vanadate composite photocatalyst prepared in Example 3 was named 3 wt% AFO / AVO.
