[0036] Please refer to the attached figure 1 , the Cs provided in Examples 1, 2, 3, and 4 of the present invention 2 AgSbCl 6 Bimetallic perovskite supported graphene-like carbon nitride (g-C 3 N 4 ) The preparation method of visible light catalyst, comprises the following steps:
[0037] 11) 1 mmol of SbCl 3 and 1 mmol of AgCl solid drug dissolved in a beaker containing 12 ml of HCl, heated to 80 °C with constant stirring to dissolve; then, 2 mmol of CsCl was added to the hot solution; soon, a precipitate formed at the bottom of the beaker; Washed with ethanol three times, and finally dried in an oven at 120-150 °C for 5-7 hours; after the oven was cooled to room temperature, take out to obtain Cs 2 AgSbCl 6 powder;
[0038] 12) Add the weighed 10g of melamine to the prepared alumina crucible, cover the lid, and place it in a muffle furnace for calcination. ~2h, the heating rate is 10~15℃ / min, finally cooled to room temperature naturally, and collected to obtain g-C ...
Embodiment 1
[0056] a Cs 2 AgSbCl 6 Bimetallic perovskite supported graphene-like carbon nitride (g-C 3 N 4 ) The preparation method of visible light catalyst, comprises the following steps:
[0057] Weigh 1 mmol of SbCl 3 and 1 mmol of AgCl solid drug substance were dissolved in a beaker containing 12 ml of HCl and heated to 80 °C with constant stirring to dissolve. Then, 2 mmol of CsCl was added to the hot solution. Soon, a precipitate formed at the bottom of the beaker. The precipitate was collected, washed three times with ethanol, and finally dried in an oven at 150 °C for 7 h. After the oven is cooled to room temperature, take out the Cs 2 AgSbCl 6 Powder; add the weighed 10g melamine into the prepared alumina crucible, cover the lid, and place it in a muffle furnace for calcination. The rate was 10°C / min, and finally cooled to room temperature naturally and collected to obtain g-C 3 N 4 Sample; 0.0016g of Cs 2 AgSbCl 6 Bimetallic perovskite and 0.8 g of g-C 3 N 4 It w...
