Electrodeposition of V2O5 on TiO2 nanorod arrays and their electrochromic properties

Abstract

This paper shows a simple approach for the electrodeposition of V2O5 nanoparticles on a TiO2 nanorod arrays substrate by combining hydrothermal and electrochemical deposition methods. The electrochemical and optical properties of the TiO2/V2O5 hybrid film have been investigated and the results show that the hybrid film has obviously better electrochemical and electrochromic properties compared with the single V2O5 thin film. The TiO2/4cir-V2O5 hybrid film shows the most improved electrochromic properties with excellent cyclic stability, outstanding transmittance modulation (50% at 780 nm) and high coloration efficiency (28 Cāˆ’1 cm2 at 780 nm). The modified electrochromic properties are mainly due to the TiO2 nanorod array structure, which contributes to improve the structural stability of the V2O5 film and benefits the intercalation/deintercalation process of Li+ ions within the V2O5 film.
