Analysis of structural morphological changes from 3DOM V2O5 film to V2O5 nanorods film and its application in electrochromic device

2D vanadium oxide inverse opal films: cycling stability exploration as an electrochromic active electrode

“…2). Similar to that found in the literature, 3,27 the anodic oxidation peaks, which were measured at the 10th cycle, for all three samples are close for the first peak, being around −0.6 V for V220-400C, −0.58 V for V430-400C and −0.59 V for V700-400C, indicating a similar behavior of Li + deintercalation. As the voltage increased, we observe another anodic peak at +0.76 V for V220-400C, +0.85 V for V430-400C and +069 V for V700-400C.…”

“…Vanadium oxides as electrochromic active materials are particularly attractive since they show polyelectrochromic behavior 1,2 as well as a fast response time 3 during the reversible intercalation/deintercalation of cations (such as Li + ) into their typical layered structure due to the multiple stable oxidation states (III–V) of vanadium in its oxides. However, similar to their application in batteries, their practical use as electrochromic (EC) active materials was limited partially due to poor cycling reversibility and stability 4 that resulted in fast fading upon cycling.…”

Multicolored inorganic electrochromic materials: status, challenge, and prospects

“…Therefore, improving the monochromatic properties and universality of color adjustment of inorganic electrochromic materials has become a hotspot in the field of electrochromic materials. 25 Currently, there are three main strategies to achieve multicolor based on inorganic electrochromic materials: intrinsic color, [26][27][28] structural color, 29,30 and stacked color (Fig. 1).…”

Ionic Liquid Promotes High Dispersion of V2O5 on 3D Porous g-C3N4 Carrier to Enhance Catalytic Oxidative Desulfurization Performance

“…The interplanar crystal spacings of 0.34 and 0.288 nm are regarded as (110) and (301) crystal faces, respectively, which are consistent with the XRD results. 16,22 EDS mapping analysis in Figure S4 revealed that C, N, O, and V elements were uniformly distributed on the catalyst. Therefore, the results of SEM, TEM, HRTEM, and EDS mapping strongly prove that the uniform loading of V 2 O 5 on the carrier 3D g-C 3 N 4 can be realized by using vanadium-based ionic liquid [(C 8 H 17 ) 3 NCH 3 ] 3 H 3 V 10 O 28 as the vanadium source and template agent.…”
