Black brookite titania with high solar absorption and excellent photocatalytic performance

Black platelike brookite with outstanding photocatalytic performance is prepared by constructing a distinct crystalline core/disordered shell structure (TiO sub(2)[at]TiO sub(2-x)) through aluminium reduction. Many oxygen vacancies and Ti super(3+) states are introduced into the distorted shell, whi...

Zusammenfassung:Black platelike brookite with outstanding photocatalytic performance is prepared by constructing a distinct crystalline core/disordered shell structure (TiO sub(2)[at]TiO sub(2-x)) through aluminium reduction. Many oxygen vacancies and Ti super(3+) states are introduced into the distorted shell, which increase the solar energy absorption and boost the photocatalytic activity.
