Electrochromic properties of porous WO3–TiO2 core–shell nanowires

WO3/TiO2 core–shell nanostructure for high performance energy-saving smart windows

“…4(a) show that the value of the peak current (cathodic current density and anodic current density) is the highest in the WT2 sample. These results suggest that the increase in current is due to the combined effect of the WO 3 core and the TiO 2 shell, which supports other recent findings [17,19]. These results were possibly caused by the WO 3 / TiO 2 core-shell nanostructure improving the kinetics of the mechanisms for intercalation and deintercalation among charges.…”

“…Reversal of the potential is scanned during an anodic wave when a distinct anodic peak was observed with a shoulder of a broad peak. It is known that WO 3 /TiO 2 exhibits a broad anodic peak and a distinct anodic peak may be due to the presence of a WO 3 /TiO 2 core-shell nanostructure [16,17]. Cathode coloration occurs with the ion insertion, while anode coloration occurs with ion extraction.…”

Progress in Electrochromics: Towards Long-Term Durability and Materials Rejuvenation for Oxide-Based Thin Films

“…Similar results were found in later studies (28)(29)(30)(31)(32), and recent work showed that Ti prevents crystallization so that lattice ordering takes place at an increased temperature when Ti is present (29,31).…”

Fabricating polypyrrole/tungsten oxide hybrid based electrochromic devices using different ionic liquids

“…However, ECDs synthesized by BMIMPF 6 and BMIMTFSI mediums exhibited weaker stability, relatively. Cyclic stability of the EC device is related to the crystallinity of the material . The results are in accordance with XRD results in a way that the weakest crystalline‐structured composite in BMIMTFSI medium has the weakest cyclic stability.…”
