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.

“…There are numerous methods reported for the fabrication of BiVO 4 , including hydrothermal treatment [15][16][17][18], sonochemical method [19], sol-gel method [20][21][22], ionothermal treatment [23], microwave-assisted route [24,25], solution combustion synthesis [26], co-precipitation process [27], molten salt method [28], reverse microemulsion process [29], aqueous method [30][31][32][33], etc. Among all of theses methods, the aqueous method provides a milder environment for the synthesis of monoclinic BiVO 4 and allows the reaction parameters as well as the properties of the products to be easily tuned.…”

BiVO 4 photocatalysts were synthesized via a facile surfactant-free method with heat treatment. The heat treatment temperatures influenced the crystal structures and morphologies. The photocatalytic performance is associated with its crystallinity, Brunauer-Emmett-Teller (BET) specific surface area, and band gap energy. The BiVO 4 photocatalyst prepared by heat treatment at 700˝C showed the highest photocatalytic activity, promoting 100% degradation of methylene blue (MB) in 60 min under visible-light irradiation. Recycling experiments results indicated that the BiVO 4 photocatalysts have excellent photo-stability, and a possible mechanism for the photocatalytic process was proposed by examining the effects of the active species involved in MB degradation. This work could provide new insights into the fabrication of highly efficient and stable BiVO 4 photocatalysts for dye degradation.

“…[23,24] The latter concept was also applied to obtain BiVO 4 doped with precious metals (e.g., Ag), composite photocatalysts such as TiO 2 /BiVO 4 and reduced graphene oxide/BiVO 4 . [25][26][27] To improvet he optical absorption properties and charge separation efficiency,C -doped BiVO 4 and C/BiVO 4 composites with carbon adsorbed at the surface of the metal oxide were introduced. [28,29] Here we report anew synthetic method for BiVO 4 using amicrowave-assisted approach based on the concept of in situ twin polymerization.…”

A new synthetic route to monoclinic bismuth vanadate using a concept adapted from a nonaqueous synthesis strategy for nanostructured organic–inorganic hybrid materials and metal oxides, introduced recently as twin polymerization, is reported. Microwave‐assisted synthesis starting from bismuth(III) tert‐butoxide and vanadium(V) oxytri(tert‐butoxide) in the presence of 2‐methoxybenzyl alcohol, 2,4‐dimethoxybenzyl alcohol, and 2‐(2‐thienyl)iso‐propyl alcohol gave hybrid materials, which were characterized by solid‐state 13C NMR spectroscopy, CH analysis, atomic absorption spectroscopy, and energy dispersive X‐ray spectroscopy. Subsequent pyrolysis resulted in nanoscale monoclinic bismuth vanadate that showed a high photocatalytic activity. The photocatalytic decomposition of model pollutants such as rhodamine B (RhB), methyl orange, methylene blue, and orange G under visible‐light irradiation using the as‐prepared bismuth vanadate samples was studied with a focus on the influence of the agglomeration behavior. The interplay between the photooxidation of RhB, induced by the excitation of the catalyst using visible light, and the photosensitized decomposition pathway is demonstrated by degradation experiments in solution and the solid state.
