“…Solar simulating light (SSL) has been frequently employed for evaluating the performance of photovoltaic cells (Senadeera et al, 2003) or photocatalysts (Yu et al, 2009;Sakai et al, 2016). Since the photovoltaic cells and photocatalysts are mostly sensitive to ultraviolet (UV) and visible (VIS) lights regions, most SSL are designed to reproduce the spectra of solar ray in these regions.…”

“…Many studies were carried out in the last few years in order to develop new compounds with narrow band gaps to increase the visible light response of photocatalysts [4,5]. Due to their high chemical stability, oxides are the most attractive class of compounds; the use of mixed metal oxides allows for an effective tailoring of the physicochemical properties.…”

Synthesis of Phase Pure Hexagonal YFeO3 Perovskite as Efficient Visible Light Active Photocatalyst

et al. 2017

Hexagonal perovskite YFeO 3 was synthesized by a complex-assisted sol-gel technique allowing crystallization at calcination temperatures below 700 • C. As determined by diffuse reflectance spectroscopy (DRS) and Tauc plots, the hexagonal YFeO 3 exhibits a lower optical band gap (1.81 eV) than the orthorhombic structure (about 2.1 eV or even higher) being typically obtained at elevated temperatures (>700 • C), and thus enables higher visible light photocatalysis activity. Structure and morphology of the synthesized YFeO 3 perovskites were analyzed by powder X-ray diffraction (XRD) and nitrogen adsorption, proving that significantly smaller crystallite sizes and higher surface areas are obtained for YFeO 3 with a hexagonal phase. The photocatalytic activity of the different YFeO 3 phases was deduced via the degradation of the model pollutants methyl orange and 4-chlorophenol. Experiments under illumination with light of different wavelengths, in the presence of different trapping elements, as well as photoelectrochemical tests allow conclusions regarding band positions of YFeO 3 and the photocatalytic degradation mechanism. X-ray photoelectron spectroscopy indicates that a very thin layer of Y 2 O 3 might support the photocatalysis by improving the separation of photogenerated charge carriers.

“…[16][17][18] The oxide has been synthesized by various means, including traditional solid state, [19][20][21] hydrothermal, 22,23 sonochemical, 24 and aqueous/coprecipitation. 16,25,26 With a bandgap of 2.4 eV, BiVO 4 absorbs well into the visible spectrum and has shown significant visible-light activity for O 2 evolution from AgNO 3 solutions, which act as the oxidizing agent. [16][17][18] The monoclinic sheelite polymorph of BiVO 4 is known to possess the highest photocatalytic activity, 16 however two other forms of the material do exist (tetragonal zircon and tetragonal sheelite).…”

BiVO₄ as a Visible-Light Photocatalyst Prepared by Ultrasonic Spray Pyrolysis

2009

BiVO 4 powders with unique particle architectures have been synthesized using ultrasonic spray pyrolysis (USP). Gases created from the evaporation of solvent and the decomposition of precursor materials shape the morphology of the particles as the solids are formed in the heated aerosol. The BiVO 4 powder was tested as oxygen evolving photocatalysts by monitoring the kinetics of O 2 formation from a AgNO 3 solution irradiated with λ > 400 nm light. USP prepared BiVO 4 was found to have significantly superior photocatalytic activity compared to commercial BiVO 4 and WO 3 , likely due to differences in particle morphology.
