Embodiment 1
[0045] Example 1: Synthesis of N,S-GQDs / CoOOH nanocomposites
[0046] Preparation of N,S-GQDs: Mix 1.0 g citric acid and 0.3 g L-cysteine into a 25 mL round bottom flask, heat up to 240 °C for 10 min in an electric heating mantle, the reactant liquefies, the color From white to pale yellow and finally to orange. The obtained liquid was dissolved in 10 mL of ultrapure water, dialyzed in ultrapure water for 8 h with a dialysis membrane (1000 Da), and the dialyzed solution was freeze-dried to obtain N,S-GQDs solid powder.
[0047] Synthesis of CoOOH nanosheets: NaOH solution (200 μL, 0.8 M) and CoCl 2 The solution (3 mL, 10 mM) was mixed evenly, and NaClO solution (200 μL, 0.2 M) was added dropwise to the mixed solution, and stirred until no brown substance was regenerated in the solution. After ultrasonicating the obtained brown suspension for 10 min, put it in a centrifuge at 4000r / min for 20 min to obtain CoOOH nanosheets, and finally wash the obtained nanosheets with pure...
Embodiment 2
[0051] Example 2: Synthesis of N,S-GQDs / CoOOH nanocomposites
[0052] The synthesis of N,S-GQDs and CoOOH nanosheets is the same as in Example 1. The average particle size of N,S-GQDs is 3.5 nm, and the size of CoOOH is 80 nm.
[0053] Synthesis of N,S-GQDs / CoOOH nanocomposites: Add 100 μL of N,S-GQDs solution to the prepared CoOOH nanosheet aqueous solution (10 μg / mL), and dilute to 15 mL with purified water. The mixture was sonicated for 10 min to prepare the N,S-GQDs / CoOOH nanocomposite solution. The obtained solution was freeze-dried to obtain N,S-GQDs / CoOOH nanocomposite solid powder for subsequent experiments.
Embodiment 3
[0054] Example 3: Synthesis of N,S-GQDs / CoOOH nanocomposites
[0055] The synthesis of N,S-GQDs and CoOOH nanosheets is the same as in Example 1. The average particle size of N,S-GQDs is 3.5 nm, and the size of CoOOH is 80 nm.
[0056] Synthesis of N,S-GQDs / CoOOH nanocomposites: Add 100 μL of N,S-GQDs solution to the prepared CoOOH nanosheet aqueous solution (60 μg / mL), and dilute to 15 mL with purified water. The mixture was sonicated for 10 min to prepare the N,S-GQDs / CoOOH nanocomposite solution. The obtained solution was freeze-dried to obtain N,S-GQDs / CoOOH nanocomposite solid powder for subsequent experiments.
