“…However, the photophysical and photocatalytic properties of BiVO 4 are strongly influenced by the way of preparation and its crystal structure. Several methods have been reported for the synthesis of BiVO 4 such as solid-state reaction [14], sonochemical [15], organic decomposition [16], precipitation [17], and hydrothermal [18]. However, these methods still have limitations such as complicated manipulation, specific requirement of equipment, and agglomeration or secondary growth often occur when we dry the wet particles separated from the reaction solution.…”

Bismuth vanadate (BiVO 4 ) powder was successfully prepared by the sol-gel method.Bismuth nitrate and ammonium vanadate were used as the starting precursors with mole ratio of 1:1 in ethanol media at 70 • C for 1 h. The yellow gel was calcined at 400-600 • C for 2 h. The phase of BiVO 4 powder was characterized by X-ray diffraction (XRD). The morphology and chemical composition of BiVO 4 powder were investigated by scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDXS). The functional groups of BiVO 4 powder was identified by Fourier transform infrared spectroscopy (FTIR) and the surface area of BiVO 4 powder was determined by Brunauer, Emmett and Teller technique (BET).

“…In order to improve the photocatalytic activity of the BiVO 4 monoclinic polymorph, different synthesis routes have been proposed in order to take control of the morphology and textural properties of the photocatalyst oxide. In this sense, besides the classical solid‐state reaction , monoclinic bismuth vanadate has been synthesized by means of layered vanadates in aqueous solution , sonochemistry , hydrothermal or solvothermal methods , coprecipitation , and sol–gel . Compared with other methods, hydrothermal or solvothermal methods provide a milder environment for the synthesis of monoclinic BiVO 4 and the reaction parameters and the properties of the products can be easily tuned.…”

Key words peanut-like BiVO 4 , visible-light-driven photocatalysts, solvothermal method, Rhodamine B (RhB).Monoclinic peanut-like BiVO 4 products have been successfully synthesized by a solvothermal method. The volume of CH 3 COOH and the concentration of NH 3 ·H 2 O were found to play important roles in the formation of this morphology. The optimal condition for preparation of highly active peanut-like BiVO 4 samples are the volume of CH 3 COOH, which was 5 ml, and the concentration of NH 3 ·H 2 O, which was 2 mol/L. The as-prepared samples were characterized by XRD, SEM, TEM, DRS, BET, and their photocatalytic activity was evaluated by photocatalytic decolorization of a Rhodamine B (RhB) aqueous solution under visible-light irradiation. The results demonstrated that BiVO 4 with peanut-like morphology was better than that of other BiVO 4 samples for photodegradation of RhB.

“…In this project we have developed high-throughput characterization techniques, including X-ray absorption fine structure (XAFS) spectroscopy to allow in situ characterization of materials without long-range ordering. This study describes the synthesis and characterization of a particular family of ceramic materials, bismuth molybdenum vanadium oxides, BiMoVOX, suitable as inorganic pigment [2] and low temperature heterogeneous oxidation catalysts [3].…”

Abstract. The high throughput synthesis and characterization of a particular family of ceramic materials, bismuth molybdenum vanadium oxides (BiMoVOX), suitable as inorganic yellow pigments and low temperature oxidation catalysts, is described. Samples, synthesized by calcination and peroxo sol-gel methods, are characterized by X-ray powder diffraction, UV-visible and XAFS spectroscopy. A combined high-throughput XRD/XAFS study of a 54 samples array, with simultaneous refinement of data of both techniques, has been performed.
