摘要: Abstract In this paper, we report enhanced electrochemical capacitance of well-aligned TiO 2 nanotube arrays with “nanograss” synthesized by anodization. The conductivity hybrid materials is improved reduction method, exhibiting an outstanding specific 14.3 mF cm −2 , which 14 times larger than pristine ones. further increases up to 20.5 mF cm 43.4% higher reduced ones selectively retention ultrasonic treatment. We expect that the electrochemical-reduction approach and controllable morphology modification offer a potential path for developing high-performance energy storage devices.
