Abstract

•Optical fibre was modified to enable side emission of light.•Immersible LED is suitable as light sources for underwater photocatalysis.•Au-TiO2 catalyst degraded EE2 and E3 under UVA and visible light.•EE2 t1/2 was 1.26 h and 0.78 h for P25 and 4 wt.% Au-TiO2 under UVA.•Optical fibre reactor showed good reusability with 94 % efficiency after 3 cycles.
