Embodiment 1
[0026] Weigh 50mg of graphene oxide into a beaker with an analytical balance, add 25mL of deionized water and use a probe to ultrasonically disperse it for 15 minutes to obtain a mixed solution A. Pour A into a polytetrafluoroethylene reactor at 180°C. After heating for 5 hours, the obtained rGO was in the form of rods. After freeze-drying, 5 mg of rGO was added to 10 mL of thiol ligand-protected gold cluster solution (1 mM) and 10 mL of ultrapure water. After ultrasonication for 45 min, a uniformly dispersed mixture B was obtained. After the membrane was washed with 150mL deionized water to form a homogeneous composite catalytic membrane. Use 0.2mM p-nitrophenol (4-NP) solution to pass through the membrane at a flow rate of 1mL / min for 2h to reach adsorption saturation, and then degrade 0.5mM, 1.0mM, and 1.5mM p-nitrophenol (4-NP) in turn. Solution, degradation effect are 100%, 100%, 100% respectively.
Embodiment 2
[0028] Weigh 50mg of graphene oxide into a beaker with an analytical balance, add 25mL of deionized water and use a probe to ultrasonically disperse it for 15 minutes to obtain a mixed solution A. Pour A into a polytetrafluoroethylene reactor at 180°C. After heating for 5 hours, the obtained rGO was in the form of rods. After freeze-drying, take 5 mg of rGO, add 5 mL of thiol ligand-protected gold cluster solution (1 mM) and 15 mL of ultrapure water, and obtain a uniformly dispersed mixture B after ultrasonication for 45 min. After the membrane was washed with 150mL deionized water to form a homogeneous composite catalytic membrane. Use 0.2mM p-nitrophenol (4-NP) solution to pass through the membrane at a flow rate of 1mL / min for 2h to reach adsorption saturation, and then degrade 0.5mM, 1.0mM, and 1.5mM 4-NP solutions in turn, and the degradation effects are respectively 100%, 96.1%, 62.1%.
Embodiment 3
[0030] Weigh 50mg of graphene oxide into a beaker with an analytical balance, add 25mL of deionized water and use a probe to ultrasonically disperse it for 15 minutes to obtain a mixed solution A. Pour A into a polytetrafluoroethylene reactor at 180°C. After heating for 5 hours, the obtained rGO was in the form of a rod. After freeze-drying, take 5 mg of rGO and add 20 mL of thiol ligand-protected gold cluster solution (1 mM). After ultrasonication for 45 min, a uniformly dispersed mixture B was obtained. After pumping B, use 150 mL to remove A homogeneous composite catalytic membrane is formed after washing excess substances with ion water. Use 0.2mM p-nitrophenol (4-NP) solution to pass through the membrane at a flow rate of 1mL / min for 2h to reach adsorption saturation, and then degrade 0.5mM, 1.0mM, and 1.5mM 4-NP in sequence, and the degradation effects are 100 %, 100%, 100%.
