Solid solutions on the base of bismuth vanadate: Preparation, structure, phase transitions, dielectric and transport properties

Recent advances in visible light Bi-based photocatalysts

“…Similarities of the components such as ionic radius, polarization properties, electronegativities, and crystal structures are required, and thermal treatment is normally used for the formation of a solid solution. Various Bi-based solid solutions have been reported and include a Ce1-xBixO2-δ (x = 0.1-0.5) solid solution fabricated by Marija et al [95] through a self-propagating method, and a (Bi1-yLay)4(V1-xMex)2O11-y (x, y < 0.2, Me = Zr, Ga, Fe, Cu) solid solution synthesized by Politova et al [96] using a solid state reaction. Shangguan et al [97,98] prepared Bi0.5La0.5VO4 and BiYWO6 solid solutions loaded with a Pt-Cr2O3 cocatalyst, and found that they both exhibited visible light photocatalytic activity toward H2 production by water splitting.…”

γ-Phase stabilized Bi4BaxV2−xO11−δ (0.0 ≤ x ≤ 0.20): Structural, thermal and conducting properties

“…Bismuth vanadate consists of a complex, layered structure, with inherent oxygen vacancies. The details of the crystal structure are reported by many researchers [4,7]. Structurally, the high temperature γ-phase is highly disordered and exhibits high ionic conductivity.…”

Oxide ion conductors based on niobium-doped bismuth vanadate: conductivity and phase transition features

“…This increment in c can be contributed by the difference in the ionic radii of the dopant cation Nb 5+ (0.69 Å) and the host cation V 5+ (0.52 Å). This can be elucidated by the ideal structure of γ-Bi 4 V 2 O 11 in which the c parameter substantially affects the phase transition in the VO layer [14][15][16], resulting in an increase in the value of c.…”
