[0032] A kind of preparation method of ternary semiconductor catalyst of the present invention, specifically carry out according to the following steps:
[0033] Step 1: Add 1 to 3 mmol of benzoyl peroxide to a mixture of 8 to 30 mL of acetone and 2-methoxyethanol and stir evenly; then add 0.2 to 0.5 mL of methacrylic acid and 0.4 ~ 1mL isopropyl titanate, continue to stir to obtain a light yellow solution;
[0034] Step 2,
[0035] Continue to add bismuth nitrate pentahydrate to the light yellow solution obtained in step 1, stir until the solution is uniform, and heat at 120°C for 60 minutes to obtain the precursor P 0 ;
[0036] Step 3,
[0037] In a 4kW ceramic fiber muffle furnace, react 0.8-2.0g of dicyandiamide at 540°C for 2h at a heating rate of 7°C / min, and naturally cool to room temperature to obtain light yellow g-C 3 N 4 ;
[0038] Step 4,
[0039] 1g precursor P obtained in step 2 0 Add to the g-C prepared in step 3 3 N 4 After grinding and mixing evenly...
