Hydrothermal synthesis of vanadium oxide nanorods and their electrochromic performance

Nanorod-like V2O5 was fabricated using a simple one-step hydrothermal method using NH4VO3 and oxalic acid as precursors. The morphology and structure of the as-prepared V2O5 nanocrystals were characterized by different techniques. Furthermore, based on the analyses of cyclic voltammetric curves and...

Description
Summary:Nanorod-like V2O5 was fabricated using a simple one-step hydrothermal method using NH4VO3 and oxalic acid as precursors. The morphology and structure of the as-prepared V2O5 nanocrystals were characterized by different techniques. Furthermore, based on the analyses of cyclic voltammetric curves and electrochromism test, the thin V2O5 nanorod film have been found to exhibit promising electrochromic performance, which can be attributed to their nanorod architecture. The as-prepared V2O5 nanocrystals are promising electrochromic candidate for potential application in smart window. [Display omitted] •We have fabricated V2O5 nanorods using a simple hydrothermal route.•V2O5 nanorods were directly assembled into FTO coated glass without seed layer.•The electrochromic performance of the V2O5 nanorods is studied.•The V2O5 nanorods could be a good candidate for fabricating smart window.
