Embodiment 1
[0056] Preparation of iron (III) of the present invention / bismuth molybdate-based composite photocatalytic material with oxygen deficiency is specifically carried out according to the following steps:
[0057] Step 1, prepare the bismuth molybdate photocatalytic material with oxygen deficiency according to the following steps:
[0058] Step 1.1, first measure 1.3mmol of Bi(NO 3 ) 3 ·5H 2 O was dissolved in 13ml of ethylene glycol solution, and then 0.65mmol of Na was added to the ethylene glycol solution 2 MoO 4 2H 2 O, finally stir until a transparent solution is obtained;
[0059] Step 1.2, first add 32.5mL of absolute ethanol to the transparent solution obtained in step 1.1 and stir for 1 hour, then transfer it to the reaction kettle and seal it, and then put the reaction kettle into an electric heating constant temperature blast drying box, The reaction was carried out at 140°C for 10 hours to obtain a mixed solution A. After the reaction was completed, the mixed sol...
