- •
Ag(Cl,Br)–Au micro-necklaces were obtained via a facile solution immersion method.
- •
Both detection and degradation of food contaminant Sudan I were realized.
- •
Reproducible SERS signals with the limit of detection of 10−10 M were achieved.
- •
Enhanced photocatalytic stability and efficiency than AgBr/AgBr–Au control samples.
