Mineralization and toxicity reduction of textile dye neutral red in aqueous phase using BiOCl photocatalysis

► Photocatalytic degradation and toxicity reduction of NR dye was carried out. ► Degradation was performed using synthesized BiOCl. ► Formation of OH verified by fluorescence technology. ► Photodegradation of textile dye reduced the acute toxicity to marine bacteria Vibrio fischeri. ► Mineralization of NR confirmed by COD and nitrate anions production.
