Embodiment 1
[0027] Weigh 0.01g of ferric chloride and 0.2g of covalent triazine organic polymer and mix them in 20mL of distilled water. After ultrasonication for 30min, heat and stir in a water bath at 80°C until the water is evaporated to dryness. Collect the solid and place it in a muffle furnace. Calcined at 250°C for 1 hour in an air atmosphere to obtain a solid sample; grind the obtained solid sample thoroughly, reflux it with methanol at 90°C for 12 hours, collect the solid and dry it at 60°C for 12 hours to obtain a 5% iron-doped covalent triazine Organic polymer visible light catalyst, denoted as Fe 5 / CTF.
Embodiment 2
[0029] Weigh 0.02g of ferric chloride and 0.2g of covalent triazine organic polymer and mix them in 20mL of distilled water. After ultrasonication for 30min, heat and stir in a water bath at 80°C until the water is evaporated to dryness. Collect the solid and place it in a muffle furnace. Calcined at 250°C for 1 hour in an air atmosphere to obtain a solid sample; grind the obtained solid sample thoroughly, reflux it with methanol at 90°C for 12 hours, collect the solid and dry it at 60°C for 12 hours to obtain 10% iron-doped covalent triazine Organic polymer visible light catalyst, denoted as Fe 10 / CTF.
Embodiment 3
[0031] Weigh 0.03g of ferric chloride and 0.2g of covalent triazine organic polymer and mix them in 20mL of distilled water. After ultrasonication for 30min, heat and stir in a water bath at 80°C until the water evaporates to dryness. Collect the solid and place it in a muffle furnace. Calcined at 250°C for 1 hour in an air atmosphere to obtain a solid sample; grind the obtained solid sample thoroughly, reflux it with methanol at 90°C for 12 hours, collect the solid and dry it at 60°C for 12 hours to obtain a 15% iron-doped covalent triazine Organic polymer visible light catalyst, denoted as Fe 15 / CTF.
