Grey Rutile TiO<sub>2</sub> with Long-Term Photocatalytic Activity Synthesized Via Two-Step Calcination.
Nanomaterials (Basel, Switzerland) 20200509 5
Colored titanium oxides are usually unstable in the atmosphere. Herein, a gray rutile titanium dioxide is synthesized by two-step calcination successively in a high-temperature reduction atmosphere and in a lower-temperature air atmosphere. The as-synthesized gray rutile TiO<sub>2</sub> exhibits higher photocatalytic activity than that of white rutile TiO<sub>2</sub> and shows high chemical stability. This is attributed to interior oxygen vacancies, which can improve the separation and transmiss ...[more]
