Embodiment 1
[0025] A series of bimetallosilicates / g-C 3 N 4 The preparation of composite photocatalyst comprises the steps:
[0026] 1) With Ce(SO 4 ) 2 4H 2 O. CoSO 4 ·7H 2 O and Na 2 SiO 3 9H 2 O raw material, take by weighing 4.043g and 2.811g Ce(SO 4 ) 2 4H 2 O and CoSO 4 ·7H 2 O mixed and dissolved in 50mL water to form solution A, 5.684g Na 2 SiO 3 9H 2 O was dissolved in 50mL water to form solution B;
[0027] 2) Slowly add solution B prepared in step 1) dropwise to solution A under vigorous stirring at 300rpm / min to form solution C;
[0028] 3) Continue to vigorously stir the solution C obtained in step 2) for 30 minutes to obtain solution D;
[0029]4) Centrifuge the D solution obtained in step 3) to obtain a precipitate, and rinse with water and ethanol three times to obtain a powder sample, and place it in a 60°C drying oven to dry overnight to obtain a dried material;
[0030] 5) Grinding the fully dried material obtained in step 4) to obtain a powdered bime...
