Fujishima et al 19 specifically provided additional details regarding the outstanding titanium dioxide photocatalyst material for environmental purification.…”

Photocatalytic Properties of Molybdenum Oxide Photoelectrode Synthesized by Spray Pyrolysis Method

“…The electrochemical impedance spectroscopy results can be used to investigate the charge carrier transfer process that occur during the PEC measurement. The semicircle is significantly depressed, which suggest efficient charge transfer in the electrode [2,15]. The impedance data is obtained by fitting the experimental Nyquist data Pt/α-MoO3 --~18 mA/cm 2 at 0.75 V, 0.5 M Na2SO4 electrolyte [36] α-MoO3/TiO2 NT Ti-Mo foil AN ~200 µA/cm 2 at 0.9 V, 0.1 M Na2SO4 electrolyte, under 1 sun AM 1.5G [37] MoS2/α-MoO3 NT GCE Hydrothermal −30 mA/cm 2 at 0.1 V vs RHE, 0.5 M Na2SO4 electrolyte, 0.8 W NIR laser irradiation [38] Notes: -SP: spray pyrolysis; AA-CVD: Aerosol-assisted CVD; FTO: fluorine-tin-oxide coated glass; RHE: reversible hydrogen electrode; SCE: saturated calomel electrode; GCE: Glassy carbon electrode; Pt: platinum; PS-CVD: powder-source CVD; AN: anodization; Ti-Mo: titanium-molybdenum alloy substrate; NT: nanotubes.…”

“…Traditionally, three distinct frequency crests can be observed in a Bode phase plot [5]. The lowfrequency crest (10 -1 -1 Hz) scope marks the Nernst diffusion statement inside the electrolyte, the mid-frequency crest (1-10 2 Hz) scope is related to the charge carriers transport at the photoelectrode/electrolyte interface, and the high-frequency crest (10 3 -10 5 Hz) scope indicates the charge carriers transport at the Pt electrode/electrolyte boundary [2,20,40]. The response in the high-frequency crest scope around 1217.75 Hz for can be assigned to the charge carriers transport at the Pt electrode/electrolyte interface.…”

“…The increase in energy demand due to increased industrialization and human population calls for enormous research efforts to develop renewable energy sources to augment fossil fuels. Solar energy is a promising candidate among the renewable energy sources [1][2][3]. Solar energy can support photoelectrochemical (PEC) water splitting to generate clean hydrogen fuel, which can be utilized for many applications such as industrial hydrogenation reactions and fuel cells [1].…”

“…Suitable semiconductors are preferred due to their unique physical, chemical, and electrical properties [1]. Titanium oxide is the first semiconductor material to be deployed for water splitting [2,3]. Materials such as ZnO, Fe2O3, SrTiO3, CdS, GaP, Ga2O3, MoO3 and others have also been reported to support water splitting reactions [4,5,7,8].…”
