Abstract

In this paper, we propose for the first time the synthesis of α-MoO3 nanorods in a one-step procedure at mild temperatures. By changing the growth parameters, the microstructure and controllable morphology of the resulting products can be customized. The average diameter of the as-prepared nanorods is about 200 nm. The electrochromic and capacitance properties of the synthesized products were studied. The results show that the electrochromic properties of α-MoO3 nanorods at 550 nm have 67% high transmission contrast, good cycle stability and fast response time. The MoO3 nanorods also exhibit a stable supercapacitor performance with 98.5% capacitance retention after 10,000 cycles. Although current density varies sequentially, the nanostructure always exhibits a stable capacitor to maintain 100%. These results indicate the as-prepared MoO3 nanorods may be good candidates for applications in electrochromic devices and supercapacitors.

Summary

Introduction

In the last few years, the problems of global warming and energy shortage have become more and more serious problems. Electrochromism and electrochemical capacitors based on layered transition metal oxides nanostructures have attracted the attention of many technologists and researchers for potential applications for energy storage because of their ability to insert the ions to a wide range of locations [1,2,3]. The electrochromic properties of MoO3 nanomaterials have attracted much attention It is one of the best candidates for the electrically induced discoloration device manufacturing materials. Its zigzag chains and special layers shape current open channels for ion intercalation or diffusion [29,30,31] This structural property makes α-MoO3 nanomaterials promising materials for electrochromism and capacitor functions. We record for the first time that controlled one-pot water bath synthesized rod-like α-MoO3 nanomaterials used for electrochromism and capacitor applications. MoO3 nanorods produced using a one-pot water bath technique are predicted to have future uses in smart windows and energy storage devices
