Embodiment 1
[0061] A preparation method for synthesizing fluorescent carbon dots using sugarcane waste molasses as a raw material comprises the following steps:
[0062] (1) Weighing 4.0 g of sugarcane molasses, putting it into a polytetrafluoroethylene-lined reactor, reacting at 240°C for 13 h, cooling to room temperature, and obtaining sugarcane molasses after pyrolysis;
[0063] (2) Add 4 mL of deionized water to the high-temperature cracked sugarcane molasses, and ultrasonicate at 80 Hz for 4 minutes to obtain a sugarcane molasses solution; the sugarcane molasses is the residue left after crystallization and separation of white sugar in the sugarcane sucrose production process black viscous liquid;
[0064] (3) Pass the sugarcane waste molasses solution through a 0.22 μm water phase filter membrane, filter it repeatedly three times, and collect the golden yellow filtrate;
[0065] (4) Drop the golden yellow filtrate solution into 200 mL of absolute ethanol for precipitation, and prec...

[0067] A preparation method for synthesizing fluorescent carbon dots using sugarcane waste molasses as a raw material comprises the following steps:
[0068] (1) Weighing 5.0 g of sugarcane molasses, putting it into a polytetrafluoroethylene-lined reactor, reacting at 250°C for 12 hours, and cooling to room temperature to obtain high-temperature cracked sugarcane molasses;
[0069] (2) Add 5 mL of deionized water to the high-temperature cracked sugarcane molasses, and ultrasonicate at 100 Hz for 3 minutes to obtain a sugarcane molasses solution; black viscous liquid;
[0070] (3) Pass the sugarcane waste molasses solution through a 0.22 μm water phase filter membrane, filter it repeatedly three times, and collect the golden yellow filtrate;
[0071] (4) Drop the golden yellow filtrate solution into 200 mL of absolute ethanol for precipitation, and precipitate a brown solid, centrifuge at a speed of 6000 round / min for 5 minutes, collect the clear solution, remove absolute etha...

[0073] A preparation method for synthesizing fluorescent carbon dots using sugarcane waste molasses as a raw material comprises the following steps:
[0074] (1) Weighing 6.0 g of sugarcane molasses, putting it into a polytetrafluoroethylene-lined reactor, reacting at 260°C for 11 hours, cooling to room temperature, and obtaining high-temperature cracked sugarcane molasses;
[0075] (2) Add 6 mL of deionized water to the sugarcane waste molasses after pyrolysis, and ultrasonicate at 120 Hz for 2 minutes to obtain a sugarcane waste molasses solution; the sugarcane waste molasses is the remaining after crystallization and separation of white sugar in the sugarcane sucrose production process waste molasses;
[0076] (3) Pass the sugarcane waste molasses solution through a 0.22 μm water phase filter membrane, filter it repeatedly three times, and collect the golden yellow filtrate;
[0077] (4) Drop the golden yellow filtrate solution into 200 mL of absolute ethanol for precipita...
