Sea urchin-like PdCuAu nanoclusters mediated photothermal enhanced Fenton catalysis for degradation of dye pollutants

This study focused on preparing sea urchin palladium-copper nanospines (PdCuAu NAs) using a one-step reduction method. PdCuAu NAs is a highly branched nanomaterial composed of nanospines, and its unique structure and trimetallic composition give it excellent Fenton catalytic activity and photothermal properties. The characterization of PdCuAu NAs was carried out using SEM, XPS, and UV-Vis techniques. Under near-infrared light, PdCuAu NAs were quickly heated to 50 ℃. Compared to traditional photocatalysts, PdCuAu NAs showed better Fenton catalytic activity in the degradation of organic dyes such as MB. Furthermore, it exhibited good photothermal stability and reusability after multiple thermal cycles and repeated use. Thus, the results showed that PdCuAu NAs had a good degradation effect on organic wastewater.
