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.

Multi-layer NixZn1−xS/Ni foam composites were synthesized by a one-step hydrothermal reaction generating in situ growth on the Ni foam. The doping of Zn into the NixZn1−xS/Ni composite constructs the multi-layer nanostructure. The as-fabricated Ni1−xZnxS/Ni foam-2 h supercapacitor electrode shows outstanding rate properties.
