Embodiment 1
[0032] Embodiment 1: preparation g-C 3 N 4 catalyst of light
[0033] (1) Weigh urea, dry it in an oven at 80 °C for 24 h, grind it and put it into a crucible, cover it, and place it in a muffle furnace at 2.5 °C min -1 The heating rate was increased from room temperature to 550 °C and calcined for 4 h.
[0034] (2) Take it out and use 1 mol L -1 Pickle with nitric acid overnight, filter with suction, wash with distilled water 5-8 times until neutral, and dry overnight in a vacuum oven.
Embodiment 2
[0035] Example 2: Preparation of 1 wt% g-C 3 N 4 / PEDOT composite material
[0036] (1) Accurately weigh 0.9 g g-C 3 N 4 and 0.2 g FeCl 3 ·6H 2 O was dissolved in 50 mL deionized water, and then sonicated for 20 min.
[0037] (2) Then add 6.7 μL EDOT, and place the mixture in the reaction vessel.
[0038] (3) Finally, place the sealed reactor in an oven at 100 °C for 10 h.
[0039] (4) After the reaction, the reaction kettle was cooled to room temperature, and the product was suction filtered, washed and dried to obtain g-C 3 N 4 / PEDOT samples.
Embodiment 3
[0040] Embodiment 3: prepare 3 wt% g-C 3 N 4 / PEDOT composite material
[0041] (1) Accurately weigh 0.9 g g-C 3 N 4 and 0.2 g FeCl 3 ·6H 2 O was dissolved in 50 mL deionized water, and then sonicated for 20 min.
[0042] (2) Then add 20.1 μL EDOT, and place the mixture in the reaction vessel.
[0043] (3) Finally, place the sealed reactor in an oven at 100 °C for 10 h.
[0044] (4) After the reaction, the reaction kettle was cooled to room temperature, and the product was suction filtered, washed and dried to obtain g-C 3 N 4 / PEDOT samples.
[0045] Such as figure 1 is the g-C of this example 3 N 4 and g-C 3 N 4 The XRD spectrum of / PEDOT, after compounding,
[0046] g-C 3 N 4 The XRD diffraction peaks of PEDOT hardly changed, and the diffraction peaks of PEDOT and other substances were not observed, which may be because the content of PEDOT is too low relative to g-C3N4.
[0047] figure 2 For the pure g-C of this embodiment 3 N 4 and g-C 3 N 4 TEM ph...
