金属（Cu、Ni、Pb）掺杂的ZnS光催化剂在可见光照射下具有光还原脱氟六氟苯的能力，Pb、Cu掺杂的ZnS的脱氟机理与Ni掺杂的ZnS不同。Pb和Cu掺杂剂在ZnS中的作用不仅是将光催化响应扩展到可见光，而且还在光还原还原中充当氧化还原反应位点。
Metal-(Cu, Ni, or Pb) doped ZnS photocatalysts have the ability to photoreductively defluorinate hexafluorobenzene under visible light irradiation; the defluorination mechanism on Pb-, or Cu-doped ZnS is different from that on Ni-doped ZnS. The role of Pb and Cu dopants in ZnS is not only to extend the photocatalytic response toward visible light but also to act as redox reaction sites in the photoreductive defluorination.
