Embodiment 1
[0038] (1) Add 0.4 mmol Bi(NO 3 ) 3 ·5H 2 O was dissolved in 16 ml glycerin to obtain precursor solution A;
[0039] (2) Add 0.4 mmol NaVO 3 2H 2 O was dissolved in 16 ml deionized water to obtain precursor solution B;
[0040] (3) Add solution A to solution B and stir vigorously to obtain solution C;
[0041] (4) The solution C was transferred to a polytetrafluoroethylene-lined autoclave, and the synthetic product D was obtained after maintaining at 120 °C for 6 h;
[0042] (5) The solvothermally synthesized product D was centrifuged at 10,000 rpm, washed with deionized water and ethanol, and dried at 60 °C for 4 h to obtain product E;
[0043] (6) Product E was calcined in a muffle furnace at 300 °C for 5 h to obtain product F;
[0044] (7) The product F is in Ar / H 2 In atmosphere at 350 ℃, Ar / H 2 (Vol: 95%: 5%) annealed under atmosphere for 10 h to obtain H-occupied BiVO 4 -OVs photocatalytic materials.
