Study on photocurrent of bilayers photoanodes using different combination of WO3 and Fe2O3

Influence of surfactants on Fe2O3 nanostructure photoanode

“…5a reveal the diffraction peaks of rhombohedral Fe 2 O 3 . A similar prevalence of the peaks has also been observed for a-Fe 2 O 3 nanostructure film in studies carried out by solegel method [13,22]. The average crystallite size has been estimated from the DebyeeScherrer equation using (110) peak:…”

“…Consequently, Fe 2 O 3 nanostructures have been used to improve photoelectrochemical performance [11,12]. These nanostructures have large surface area, which provides a direct pathway for electrons to transfer [13]. Metal oxide nanostructures can be prepared by sputtering, electrospinning, chemical vapor deposition or solegel [14].…”

Sandwich-structured TiO2 inverse opal circulates slow photons for tremendous improvement in solar energy conversion efficiency

“…41,42 For the photodegradation evaluation, all inverse opal and nc-TiO 2 films were fabricated on glass quartz substrate while for photoelectrochemical water splitting all films were fabricated on FTO (7 Ω/sq) substrate. In both PEC and photodegradation experiments, the film was placed in the cell at the normal angle to the light source.…”

Sol-Gel Synthesized Semiconductor Oxides in Photocatalytic Degradation of Phenol

“…The semiconductor properties of -Fe 2 O 3 are the same as WO 3 , which can be seen in the position of band gaps relative to the standard hydrogen electrode. WO 3 has chemical stability in acidic medium and electrolyte solutions as well as photoactivity in the near ultraviolet and blue regions of solar spectrum [10]. According to Daneshvar et al nanosized ZnO is a suitable alternative to TiO 2 due to the band gap energy.…”
