Green nanotechnology plays an important role in designing environmentally-benign and sustainable synthesis techniques to provide safer products for human health environments. In this context, the of bismuth vanadate (BiVO4) nanoparticles (NPs) based on green chemistry principles with advantages eco-friendliness, cost-effectiveness, simplicity has been explored by researchers. Despite these tech...

In this study, the photocatalytic degradation of azo-dye acid orange 10 was investigated using titanium dioxide catalyst suspension, irradiation with ultraviolet-C lamp and bismuth vanadate under visible light of light-emitting diode lamp. Response surface methodology was successfully employed to optimize the treatment of acid orange 10 dye and assess the interactive terms of four factors. The ...

Bismuth vanadate (BiVO4) is a promising photoelectrode material for the oxidation of water, but fundamental studies of this material are lacking. To address this, we report electrical and photoelectrochemical (PEC) properties of BiVO4 single crystals (undoped, 0.6% Mo, and 0.3% W:BiVO4) grown using the floating zone technique. We demonstrate that a small polaron hopping conduction mechanism dom...

The pursuit of low-cost, high-efficiency co-catalysts that are free noble metals has become an area considerable interest in the field photocatalysis over past few years. In this work, a series cobalt phosphide (CoP 0.125–1.00 wt.%)-promoted bismuth vanadate (BiVO4) photocatalysts was synthesized and physicochemical characterized by means X-Ray diffraction, nitrogen isotherm absorption diffuse-...

We study the native defects in bismuth vanadate using hybrid density functional theory. pay special attention to where excess charges localize by considering different polaronic distortions and find that charge localization has a profound effect on local chemical environment around certain defects. In particular, oxygen dimerization may occur presence of acceptor On basis Fermi level pinning du...

Bismuth vanadate (BiVO4) is a narrow-bandgap semiconductor (~2.41 Ev) that responds to visible light. The efficiency of degradation organic dyes indexed by methylene blue (MB). After 150 min, the MB pure BiVO4 was about 20%. Its adsorption performance and electron–hole pair migration ability are weak, photocatalytic activity needs be improved. doped with rare earth ions can facilitate separatio...

Photoelectrochemical water splitting to generate H2 and O2 using only photon energy (with no added electrical energy) has been demonstrated with dual n-type-semiconductor (or Z-scheme) systems. Here we investigated two different Z-scheme systems; one is comprised of two cells with the same metal-oxide semiconductor (W- and Mo-doped bismuth vanadate), that is, Pt-W/Mo-BiVO4, and the other is com...

We report that oxide composite electrodeposition can be used for the facile preparation of metal-doped BiVO4 photoelectrodes for photoelectrochemical water oxidation. The photoactivity of electrodeposition film was improved by the addition of a small amount of tungstic acid particles during the electrodeposition. These particles are incorporated in the deposit and finally generate tungstendoped...
