Embodiment 1
[0079] Example 1: An iron-based composite absorbing material:
[0080] S101: Under stirring at 180r / min, add 10mL of methyltriethoxysilane to 200mL of 70vol% ethanol solution, then add 25mL of 12% hydrochloric acid, continue stirring for 1h, raise the temperature to 45°C and stir for 24h; then add 3mL of 25% ammonia water, after stirring for 30min, add 0.45g of iron porphyrin, then stir for 30min, let it stand for 1h, and place it at a constant temperature of 45°C to form a gel; after the gel is formed, add 3mL of ethanol / ethyl orthosilicate mixture (volume Ratio 1:4), aging at room temperature for 24 hours, drying at 50°C to constant weight to obtain a porous matrix material doped with iron porphyrin, material thickness 2mm;
[0081] S102: Dissolve 10g of urea and 3g of zinc acetate in 200mL of ultrapure water, then add 30g of ethylenediamine, stir at 300r / min at room temperature, heat at 185°C for 8h, and cool down to room temperature naturally to obtain a brown solution, fi...
Embodiment 2
[0085] Example 2: Another iron-based composite absorbing material:
[0086] S101: Stirring at 180r / min, add 10mL of methyltriethoxysilane to 300mL of 70vol% ethanol solution, then add 20mL of 15% hydrochloric acid, continue stirring for 1h, raise the temperature to 45°C and stir for 24h; then add 5mL of 22% ammonia water, after stirring for 30min, add 0.6g of iron porphyrin, then stir for 30min, let it stand for 1h, and place it at a constant temperature of 45°C to form a gel; after the gel is formed, add 3mL of ethanol / ethyl orthosilicate mixture (volume Ratio 1:4), aging at room temperature for 24 hours, drying to constant weight at 50°C to obtain a porous matrix material doped with iron porphyrin, with a thickness of 2mm;
[0087] S102: Dissolve 10g of urea and 2.5g of zinc acetate in 200mL of ultrapure water, then add 25g of ethylenediamine, stir at 300r / min at room temperature, heat at 185°C for 8h, and naturally cool to room temperature to obtain a brown solution with a ...
Embodiment 3
[0091] Example 3: Another iron-based composite absorbing material:
[0092] S101: Under stirring at 300r / min, add 10mL of methyltriethoxysilane to 300mL of 70vol% ethanol solution, then add 25mL of 20% hydrochloric acid, continue stirring for 1h, raise the temperature to 50°C and stir for 24h; then add 4mL of 20% ammonia water, after stirring for 30min, add 0.5g iron porphyrin, then stir for 30min, let it stand for 1h, and place it at a constant temperature of 45°C to form a gel; after the gel is formed, add 4mL ethanol / ethyl orthosilicate mixed solution (volume Ratio 1:4), aging at room temperature for 24 hours, drying at 45°C to constant weight to obtain a porous matrix material doped with iron porphyrin, material thickness 2mm;
[0093] S102: Dissolve 12g of urea and 4g of zinc acetate in 400mL of ultrapure water, then add 35g of ethylenediamine, stir at 600r / min at room temperature, heat at 190°C for 6h, and cool to room temperature naturally to obtain a brown solution, wh...
