“…The mechanism of the electrodeposition can be illustrated as follows: the dimeric peroxytungstate [(O 2 ) 2 W(O)·O·W(O)(O 2 ) 2 ] 2– (W 2 O 11 2– ), tungsten is in a +VI oxidation state and (O 2 ) denotes a peroxide ligand which is formed in deposition electrolytes by dissolving Na 2 WO 4 into acidic H 2 O 2 solutions, which undergoes a reduction and gives rise to tungsten trioxide and molecular oxygen during the electrodeposition procedure. 37 , 38 The reaction can be described as follows: 2WO 4 2– + 4H 2 O 2 → W 2 O 11 2– + 2OH – + 3H 2 O H x WO 3 → WO 3 + x H + + x e – …”

“…Yu's group proposed a three‐step approach of the colloidal crystal template‐assisted electrodeposition method to produce WO 3 . [ 49 ] In typical experiments, a PS microsphere is used as a patchy template for bowl‐like WO 3 synthesis. PS nanospheres are applied extensively in the design and synthesis of nanomaterials.…”

Contourable design and synthesis in nanomaterial morphology are among the most attractive fields in material science. Among the various nanomaterials, hollow bowl‐like nanomaterials have shown promising potential and achieved great success in many different domains, such as lithium‐ion batteries, supercapacitors, and electro‐ and photochemical catalysts. The unique physicochemical properties of hollow bowl‐like nanomaterials have attracted enormous interest from scientists worldwide. Here, recent researches into bowl‐like nanomaterials, including: (i) synthesis methods, such as the no‐template, no‐patchy template, and patchy template methods; (ii) applications in lithium/sodium/potassium ion‐based batteries, microwave absorption, water‐splitting reactions, and so on are reviewed; and (iii) the problems and challenges are also discussed.

“…The peroxide ligand was formed in deposition electrolytes, when Na 2 WO 4 •2H 2 O was dissolved in acidic H 2 O 2 solutions, which then reduced to WO 3 and molecular oxygen during the electrodeposition processes. 17,26,27 These processes are described in Equations 2, 3, and 4.…”

To develop an economical, efficient, and highly stable electrode having high transmittance modulation, thin films of tungsten trioxide (WO 3 ) were deposited on an Indium-doped tin oxide (ITO) glass substrate by using simple one-step pulse voltage electrodeposition (PVE) and continuous voltage electrodeposition (CVE) routes. Electrochemical and optical analyses demonstrated that the WO 3 electrode prepared by PVE possessed high switching speed, high coloration efficiency, and excellent cyclic stability. Moreover, its stable performance in the colored state extended for a long duration even after the voltage was cutoff. The coloration efficiency values were determined to be 69.00 and 43.00 cm 2 /C for W-PVE-600s and W-CVE-200s, respectively. The excellent electrochemical and electrochromic properties were mainly attributed to large surface area of W-PVE-600s, which facilitated charge transfer and promoted insertion/exertion of H + ions in electrolytes better than the WO 3 electrode prepared by conventional methods. The significant electrocatalytic activity and stable performance have proved that the proposed W-PVE-600s film can be an alternative to conventional electrodes used in smart window technology applications.
