“…Especially, metal oxide semiconductor photocatalysts have been widely studied for environment cleaning and for hydrogen generation from water splitting [4][5][6]. Metal vanadate materials (MVO 4 where M = Bi, In, Fe, Ca, Sm, etc.) have been widely investigated as possible active materials for visible light-driven photocatalysts [7][8][9][10].…”

“…Since last decade, much attention has been paid to indium vanadate (InVO 4 ) as visible light active photocatalytic material because of its huge potential for degradation of organic pollutants [15,16]. Several methods have been used for preparation of BiVO 4 and InVO 4 photocatalyst such as solidstate reaction [17], co-precipitation [18,19], and hydrothermal method [20][21][22]. Hydrothermal method has been rapidly developed due to rapid heating, faster kinetics, homogeneity, higher yield, reproducibility, and energy saving compared to other approaches [23][24][25].…”

A highly efficient and visible light responsive photocatalyst was developed by indium vanadate (InVO 4 )/ bismuth vanadate (BiVO 4 ) composite photocatalyst. The samples were characterized by X-ray diffraction (XRD), Brunauer-Emmett-Teller, scanning electron microscopy, transmission electron microscopy (TEM), UV-Vis diffuse reflectance spectra, XPS, zeta potential, and photoluminescence techniques. The XRD, TEM, and XPS results indicated the prepared sample was actually a two-phase composite: InVO 4 and BiVO 4 . Photocatalytic activities of all catalysts were evaluated for the degradation of methylene blue in aqueous solution under visible light irradiation. The highest activity was obtained in the InVO 4 /BiVO 4 composite using 0.8:0.2 mol ratio of InVO 4 :BiVO 4 . On the basis of the calculated energy band positions, the mechanism of enhanced photocatalytic activity was discussed.

“…To the best of our knowledge, preparation and characterization of BiVO4/CeO2 composite have not been previously reported, therefore this work aims to synthesize and elucidate the physical and optical properties of this novel composite material. Many methods used for composite synthesis include hydrothermal treatment, solid state reaction, precipitation, sol-gel, and sonochemical synthesis [8][9][10][11][12][13][14][15][16][17].…”

Abstract. Novel BiVO4/CeO2 nanocomposites were synthesized by the hydrothermal method combined with the homogeneous precipitation method. The mole ratios of BiVO4:CeO2 were 0.4:0.6, 0.5:0.5, and 0.6:0.4. The obtained BiVO4/CeO2 nanocomposites were characterized by X-ray diffraction (XRD) for phase composition and crystallinity. Particle sizes, morphology and elemental composition of BiVO4/CeO2 nanocomposites were examined by scanning electron microscopy (SEM), transmission electron microscopy (TEM), and energy dispersive X-ray spectroscopy (EDS). The Brunauer, Emmett and Teller (BET) adsorption-desorption of nitrogen gas for specific surface area determination at the temperature of liquid nitrogen was performed on all samples. UV-vis diffuse reflectance spectra (UV-vis DRS) were used to identify the absorption range and band gap energy of the composite catalysts. The results indicated that BiVO4/CeO2 samples retained monoclinic scheelite and fluorite structures. The morphologies of nanocomposite samples consisted of rod-like, plate-like and spheroidal shapes. Specific surface area (SSABET) of the novel synthesized catalysts drastically increased from 38-62 m 2 /g whereas an average BET-equivalent particle diameter (dBET) significantly decreased from 30-12 nm, upon increasing the amount of CeO2 in the BiVO4/CeO2 composite. The absorption spectra of all nanocomposite samples were shifted to the visible region, suggesting the potential application of this novel composite as an active visible-light driven photocatalyst.
