[0024] 1. Catalyst synthesis
[0025] (1) Preparation of graphene-like carbon nitride: Weigh 6.5g of urea into a 15ml porcelain crucible, compact it slightly with a medicine spoon, and cover the crucible lid. Place the above-mentioned porcelain crucible in a muffle furnace at 550℃ for 2 hours at a constant temperature of 8℃ / min. The yellow product obtained is graphene-like carbon nitride (g-C 3 N 4 ).
[0026] (2) Preparation of nitrogen-doped graphene quantum dots: Dissolve 0.5254 g of citric acid and 0.6006 g of urea in 12 ml of deionized water, add to a 50 ml reaction kettle after being fully dissolved, and place it in a blast drying at 160°C Keep in a constant temperature box for 8 hours to obtain nitrogen-doped graphene quantum dot solution (N-GQDs).
