“…There are several semiconductors with large band gaps that have been used to fabricate photoelectrodes, including TiO 2 [38], WO 3 [39], SrTiO 3 [40], BaTiO 3 [41], SnO 2 [42], and ZnO [43]. These semiconductors have shown good stability in an aqueous electrolyte but only absorb 4% of the solar spectrum in the ultraviolet region.…”

Available online xxxKeywords: AACVD Metal oxide Thin film Photoelectrochemical cells Water splittingHydrogen production a b s t r a c t Hydrogen energy has emerged as an alternative energy source. There are many processes for hydrogen production, which include both reforming and non-reforming hydrogen production. This paper reviews the benefits of photoelectrochemical (PEC) water splitting as a promising method for the production of hydrogen. Consequently, fabrication of efficient photoelectrode is crucial to achieve high performance cells. Aerosol-assisted chemical vapor deposition (AACVD) is discussed as a promising fabrication method for the materialization of thin films in terms of their homogeneity and uniformity. From this perspective, we discuss the AACVD process and the influence of the deposition parameters on PEC water splitting.

“…The sample group also found that the BaTiO 3 film was a potential candidate photoelectrode for PEC water splitting due to its extraordinary stability in aqueous environments. 99 The fabricated BaTiO 3 thin films are irradiated by 120 MeV Ag 9+ irradiation at four different fluences (1 × 10 11 , 2 × 10 11 , and 3 × 10 12 ions per cm 2 ). At a fluence of 1 × 10 11 ions per cm 2 , the BaTiO 3 film achieved a maximum photocurrent density of 1.78 mA cm −2 at 0.4 V vs. SCE (Fig.…”

“…Due to its high relative permittivity and low dielectric loss tangent, barium titanate is most typically used in capacitors, but frequently also in other energy-storage devices. Coatings with thicknesses between 10 µm and 1 mm are considered thick films [2,3]. The properties of these layered structures are usually considered to be comparable with bulk materials, but various aspects of the rapid solidification of thermally sprayed thick films influence their microstructure and properties.…”

Barium titanate coatings were, for the first time, sprayed by a high feed-rate plasma torch with water stabilization of the plasma. Two power levels of the torch were applied for spraying to cover steel substrates. Various substrate preheating levels from 125 °C to 377 °C were used to modify cooling conditions. Microstructure and phase composition including crystallinity quantification were observed. Dielectric measurements proved that the relative permittivity between 300 and 400 coatings is too temperature sensitive over 170 °C but fits the requirements of the EIA temperature coefficient between room temperature and 170 °C. Simultaneously, the loss tangent remains rather low, between 0.02 and 0.07, in a broad range of temperatures and frequencies. Annealing was performed in air to heal the oxygen deficiency, but only modified the microstructure insignificantly. The dielectric properties of as-sprayed and annealed samples were discussed, with the main finding that the temperature coefficient of permittivity was improved by annealing. This study contributes to the search for the suitability of plasma-sprayed BaTiO3 coatings for application in the electrical industry, namely by the optimization of conditions for high feed-rate spraying.
