摘要：The amorphous TiO₂ derived from hydroxylation has become an effective approach for the enhancement of photocatalytic activity of TiO₂ since a kind of special black TiO₂ was prepared by engineering disordered layers on TiO₂ nanocrystals via hydrogenation. In this contribution, we prepared totally amorphous TiO₂ with various degrees of blackness by introducing hydroxyls via ultrasonic irradiation, through which can we remarkably enhance the photocatalytic activity of TiO₂ with improved light harvesting and narrowed band gap.
