    摘要： The present application relates to a sterilizing and environment-friendly composite plating layer, a preparation method thereof and a sterilizing and environment-friendly product. The sterilizing and environment-friendly composite plating layer includes: a semi-bright nickel layer, a high-sulfur nickel layer and an environment-friendly white chromium composite sterilizing layer; the semi-bright nickel layer is adapted to be positioned on a substrate having a sterilizing requirement; the high-sulfur nickel layer is disposed on the surface of a side of the semi-bright nickel layer away from the substrate; the environment-friendly white chromium composite sterilizing layer is disposed on the surface of a side of the high-sulfur nickel layer away from the substrate; the environment-friendly white chromium composite sterilizing layer has a nano-needle structure and is formed by a composite raw material containing sterilizing ammonium salt, and the concentration of the sterilizing ammonium salt in the composite raw material is 50-100 g/L. The sterilizing and environment-friendly composite plating layer and the sterilizing and environment-friendly product of the present application can be prepared directly by an electroplating method, and can have good broad-spectrum sterilizing effect without spraying antibacterial materials containing nano Ag + , Cu 2+ , and the sterilizing effect can be directly displayed.
