文摘
- •
The formation of oxygen vacancy was affected by anodic oxidation time and annealed atmosphere.
- •
The optimum anodic oxidation time of black TiO2 nanotube arrays annealing in argon atmosphere has been proved.
- •
The black TiO2 nanotube arrays prepared for 6 h exhibited excellent photoelectrocatalytic performance.
- •
A possible of formation oxygen vacancies mechanism was proposed based on the preparation experiments.
