A WO3/Ag–Bi oxygen-evolution catalyst for splitting water under mild conditions

Nanostructured Tungsten Trioxide Thin Films Synthesized for Photoelectrocatalytic Water Oxidation: A review

“…[33] For instance, Yang et al synthesized WO 3 films on indium-doped tin oxide (ITO) glass by performing the continuous cathodic electrodeposition method. Zhao et al [36] investigated the WO 3 /Ag-Bi photocatalyst and found that the photocatalyst showed excellent catalytic activity for water splitting. Vijayalakshmi and co-workers studied the effect of different deposition current densities on the physical and chemical properties of WO 3 thin films.…”

“…Moreover, the element ratio of the composite also has a strong effect on the photocatalytic activity. [36] Wei et al synthesized WO 3 /n-Cu 2 O and WO 3 /p-Cu 2 O composite films by consecutive cathodic electrodeposition and found that the photoactivity of WO 3 /p-Cu 2 O was higher than that of pure WO 3 and p-Cu 2 O alone. [68] Yagi et al reported a unique approach for the synthesis of WO 3 /[Ru(bpy) 3 ] 2 + /PSS composite films, that is, simple electrodeposition from a colloidal solution containing peroxotungstic acid and [Ru(bpy) 3 ] 2 + stabilized by PSS.…”

“…They found that the film thickness was constant (0.62 AE 0.026 mm) and that the maximum absorption was at l max = 459 nm. Zhao et al [36] investigated the WO 3 /Ag-Bi photocatalyst and found that the photocatalyst showed excellent catalytic activity for water splitting. The WO 3 /Ag-Bi photocatalyst showed a high O 2 evolution rate of 30.85 mmol h À1 , a high faradaic efficiency of 91.3 %, and a low O 2 evolution overpotential of 290 mV.…”

Co3O4 Nanorods—Efficient Non-noble Metal Electrocatalyst for Oxygen Evolution at Neutral pH

“…Ahn and Tilley have reported nanostructured Co(PO 3 ) 2 as anode material for oxygen evolution at neutral pH, at an overpotential of 310 mV at 1 mA/cm 2 [22]. Zhao et al have studied WO 3 /Ag-B-based oxygen evolution catalyst which works under mild conditions for water oxidation [23]. In fact, it is a great challenge to enhance the activity and stability of a catalyst near neutral medium, because most of the transition metal oxides are not stable in neutral medium under water oxidation conditions [24].…”

Ultrathin, Porous and Oxygen Vacancies‐Enriched Ag/WO3−x Heterostructures for Electrocatalytic Hydrogen Evolution

“…Zhao et al. prepared a novel WO 3 /Ag‐B i oxygen‐evolution catalyst for water splitting under mild conditions . Therefore, the exploration of efficient electrocatalysts with both increased active sites, improved conductivity and exquisite nanostructures plays vital roles in electrochemical water splitting.…”
