Example Embodiment
[0016] Example 1
[0017] (1) First, prepare CdS, under ultrasonic treatment, thiourea and CdCl 2 were dispersed in 10 mL of ethylenediamine and continued to be sonicated. The mixture was transferred to the autoclave, sealed and kept at 160°C for 48 hours. After natural cooling to room temperature, the solid product was collected manually and thoroughly washed by centrifugation with deionized water for 3-6 times and then placed in an oven to dry for 12 hours to obtain a CdS sample and grind it for use in the next step.
[0018] (2) Preparation of Cu 5 FeS 4 First, weigh 0.0990 g CuCl and 0.2730 g FeCl 3 ·6H 2 O was dispersed in 15 mL of ethylenediamine, respectively, the two solutions were mixed after sonication for 15 min, and a 4-fold excess of (NH 4 ) 2 S solution. Then, the solution was transferred to a 50 mL reaction kettle with a Teflon lining, and after reacting at 180 °C for 24 hours, the black solid was washed with deionized water and absolute ethanol for 5 to...

[0020] Example 2
[0021] As described in Example 1, the difference is that Cu is added in step (2) 5 FeS 4 was adjusted to 0.25 mL, and the final catalyst contained 0.25 wt% Cu 5 FeS 4 0.25 wt% CdS / Cu 5 FeS 4 Plasmonic composite photocatalysts.
Example Embodiment
[0022] Example 3
[0023] As described in Example 1, the difference is that Cu is added in step (2) 5 FeS 4 was adjusted to 0.75 mL, and the final catalyst contained 0.25 wt% Cu 5 FeS 4 0.25 wt% CdS / Cu 5 FeS 4 Plasmonic composite photocatalysts.
