We study oxygen vacancies in the tetragonal scheelite phase of bismuth vanadate and identify stable oxygen-deficient structures. Upon subjecting these to variable-cell optimization, we find that give rise significant structural distortions, degree which exhibits a vacancy concentration dependence. Furthermore, show distortions splitting powder X-ray diffraction peaks, yielding patterns similar ...

The influence of hydrothermal synthesis, thermal post-treatment at 500 °C and Mo content on a series of Bi1-x/3V1-xMoxO4 (0.02 < x < 0.15) photocatalysts was investigated for methylene blue (MB) degradation and O2 evolution. As Mo incorporation stabilizes the formation of tetragonal BiVO4 phases, only calcined Bi0.99V0.98Mo0.02O4 compounds showed good photocatalytic performance in MB decomposit...

BiVO4 thin film photoanodes were grown by vapor transport chemical deposition on FTO/glass substrates. By controlling the flow rate, the temperatures of the Bi and V sources (Bi metal and V2O5 powder, respectively), and the temperature of the deposition zone in a two-zone furnace, single-phase monoclinic BiVO4 thin films can be obtained. The CVD-grown films produce global AM1.5 photocurrent den...

< Hybrid-phase BiVO4 with different hmono was controlling synthesized by hydrothermal method. < The hybrid-phase BiVO4 takes on petal-like structure when hmono reaches over 60%. < The composite BiVO4 with hmono 1⁄4 92.73% presents the best photocatalytic activity. < Possible mechanism for its high efficiency was put forward. a r t i c l e i n f o

Monodispersed monoclinic BiVO4 nanorods grown along the [010] direction were prepared using a one-step low temperature hydrothermal method in the presence of the low-cost, nontoxic sodium oleate serving as a chelating agent. The BiVO4 nanorods with diameters of 15-20 nm possess a huge specific surface area as large as 28.2 m(2) g(-1), which can endow them with high photocatalytic activity and s...

Monoclinic BiVO4 with multiple morphologies and/or porous structures were fabricated using the hydrothermal strategy. The materials were characterized by means of the XRD, Raman, TGA/DSC, SEM, XPS, and UV-Vis techniques. The photocatalytic activities of the BiVO4 materials were evaluated for the degradation of Methyl Orange under visible-light irradiation. It is observed that pH value and surfa...

In recent years, BiVO4 has drawn much attention as a novel photocatalyst given its excellent ability to absorb visible light. This work reports the development of Ag-modified BiV1-xMoxO4 composites through a facile hydrothermal synthesis with the subsequent photoinduced reduction of Ag+ at almost neutral pH conditions. Metallic Ag nanoparticles were deposited on the (040) facet of Mo-doped BiVO...

The cation deficient complex oxides of (Ca/Sr)MoO4 - BiVO4 Bi2Mo3O12 triple system are promising photocatalysts and pigments. Compounds with general formula Ca1−1.5x-yBix+yФxMo1-yVyO4 Sr1−1.5x-yBix+yФxMo1-yVyO4 were synthesized byconvention solid state technique in the range 550–720 °C. Two wide regions solutions (ordinary superstructured scheelite-type phases respectively) found for each syste...
