Despite a favourable morphology, anodized and ordered TiO2 nanotubes are incapable of showing electrochromic properties in comparison to many other metal oxide counterparts. To tackle this issue, MoO3 of ~5 to 15 nm thickness was electrodeposited onto TiO2 nanotube arrays. A homogenous MoO3 coating was obtained and the crystal phase of the electrodeposited coating was determined to be α-MoO3. The electronic and optical augmentations of the MoO3 coated TiO2 platforms were evaluated through electrochromic measurements. The MoO3/TiO2 system showed a 4-fold increase in optical density over bare TiO2 when the thickness of the MoO3 coating was optimised. The enhancement was ascribed to (a) the α-MoO3 coating reducing the bandgap of the composite material, which shifted the band edge of the TiO2 platform, and subsequently increased the charge carrier transfer of the overall system and (b) the layered morphology of α-MoO3 that increased the intercalation probability and also provided direct pathways for charge carrier transfer.
