Low temperature synthesis of iodine-doped TiO2 nanocrystallites with enhanced visible-induced photocatalytic activity

▶ Synthesis visible-activated I-TNCs at temperature as low as 120 °C. ▶ I doping, crystallization and mesoporous structure achieved simultaneously. ▶ I-TNCs promote photocatalytic activity under visible light irradiation. ▶ I-TNCs were efficiently recycled without significant loss in activity.
