“…First, the basal spacing of MgAl LDH is considerably increased, as is visible with the increase of the d values of the 00 l reflections of around 0.5 nm (ionic orientation of ferrocyanide anions) [59]. This reflection is also greatly shifted toward low values of the 2Â angle, which may indicate the departure of chloride anions from the interlayer space, subsequently displaced by ferrocyanide anions from the electrolyte as already suggested by Villemure et al [60]. On the other hand, the XRD pattern of the ZnAl LDH modified electrode does not differ from that of the freshly prepared film; therefore, no change in the basal spacing, indicating that any intercalation of the ferrocyanide anions is never obtained Fig.…”

“…A fundamentally different approach is a synthesis of nickel hydroxide compounds intercalated with large ions. Thus, researchers [28] It can be summarized that some large, multivalent cations and anions, intercalated into the nickel hydroxide lattice, can improve electrochromic performance of nickel hydroxide. Considering these facts, it was decided to study the influence of 2 4 WO anion on electrochromic properties of nickel hydroxide.…”

“…Considering these facts, it was decided to study the influence of 2 4 WO anion on electrochromic properties of nickel hydroxide. While the idea itself seemed interesting, no such data had been found in the reviewed literature [28][29][30][31].…”

“…Since it's known that the color change rises from the penetration and removing of the anions to the oxidized cationic films. 28,29 The suitability of the anion size to the porosity of the film determines the electrochromic character of the films. Fig.…”
