CN/NCD/ZFL photocatalyst, application thereof and antibiotic wastewater treatment method

The invention discloses a CN/NCD/ZFL photocatalyst, application thereof and an antibiotic wastewater treatment method. The CN/NCD/ZFL photocatalyst is prepared through an in-situ deposition-calcination method, the charge carrier transfer capacity of the catalyst is enhanced by forming a Z-type graphite-like carbon nitride/zinc-iron layered double-metal hydroxide heterojunction, the light response range is widened, and the visible light utilization rate and the charge transfer capacity are further improved through nitrogen-doped carbon dots. The nitrogen-doped carbon dot composite graphite-like carbon nitride/zinc-iron layered double hydroxide Z-type heterojunction photocatalyst prepared by the invention can effectively respond to visible light and generate related active species, and tetracycline in water is efficiently degraded. 本发明公开了一种CN/NCD/ZFL光催化剂及其应用和抗生素废水处理方法。该CN/NCD/ZFL光催化剂通过原位沉积-煅烧法制备得到，通过形成Z型类石墨相氮化碳/锌铁层状双金属氢氧化物异质结增强了催化剂的电荷载流子转移能力，增加了光响应范围，进一步通过氮掺杂碳点提高可见光光利用率及电荷传输能力。本发明制备的氮掺杂碳点复合类石墨相氮化碳/锌铁层状双金属氢氧化物Z型
