Enhanced photocatalytic activity of iron doped zinc oxide nanowires for water decontamination

► ZnO/Fe nanowires were grown on glass substrates using aqueous solutions. ► Photocatalytic activities were investigated for degradation of organic contaminants in water. ► ZnO/Fe nanowires show enhanced photocatalytic activity for all cases. ► The photocatalyst is suitable for breaking down of organic materials under solar radiation.
