Ag/AgCl@chiral TiO2 nanofibers are synthesized to tune the angle of the incident visible light through the chiral structure of the TiO2 nanofibers, intensifying the surface plasmon resonance effect of the supported Ag/AgCl materials, which are proven to be a highly active and stable visible light photocatalyst for the degradation of 17-β-ethinylestradiol.
