Enhanced photoelectrocatalytic performance of Zn-doped WO3 photocatalysts for nitrite ions degradation under visible light

Tungsten-based nanomaterials (WO 3 & Bi 2 WO 6 ): Modifications related to charge carrier transfer mechanisms and photocatalytic applications

“…Thus, WO 3 behaves as photoanode and doped metal oxides served as photocathode [87]. Interestingly, doping of Zn 2+ failed to trap the CB electrons due to its filled electronic configuration and therefore suppressed the hydrogen evolution [87], while improved the decomposition of nitrite under applied bias, with NaCl electrolyte [88]. The chloride similar to hydroxide ion can be oxidized by the VB hole directly to produce chlorine radical, which also M a n u s c r i p t 14 reacts with nitrite in the degradation process.…”

Electrochemical Preparation and Characterization of Surface-Fluorinated TiO2 Nanoporous Film and Its Enhanced Photoelectrochemical and Photocatalytic Properties

“…The incident photon to current efficiency (IPCE) was measured using a 250 W xenon lamp (SVX 1450, Müller Germany) equipped with a monochromator (Acton Spectra Pro-150, U.S.A.) that was used as light source. 23,24 The photon density of monochromatic light was monitored by an irradiatometer (S370, UDT Instruments, and U.S.A.).…”

Influence of physicochemical–electronic properties of transition metal ion doped polycrystalline titania on the photocatalytic degradation of Indigo Carmine and 4-nitrophenol under UV/solar light

“…Semiconductors like Bi 12 TiO 20 [2], Nb 2 O 5 [3], Sm 2 Ti 2 S 2 O 5 [4], Bi 2 O 3 [5], ZnWO 4 [6], Bi 2 WO 6 [7], NaTaO 3 [8], CaIn 2 O 4 [9], WO 3 [10], TiO 2 [11], Fe 2 O 3 [12], ZnO [13], etc, finds extensive application either in water splitting/degradation of organic compounds. Among the various semiconductors, TiO 2 is extensively used photocatalyst due to its chemical and biological inertness, water insolubility, non-toxicity, resistance against photo-chemical corrosion and its cheap availability.…”
