SEM images of BiVO 4 thin film. a Surface and b cross
Mo-doped high crystalline BiVO4 thin films with thickness 130 nm and morphology of small nano-sized islands on the surface (RMS = 5.08 nm) contributed well to the amplification of photocatalytic...
Octadecahedral BiVO4 with exposed high-reactivity {121} facets …
Scanning electron microscopy (SEM) images reveal that BiVO 4 displayed an octadecahedron morphology with a length ranging from 1 to 2 μm and a thickness between 0.7 and 1 μm (Fig. S2). Notably, the exposed O-BiVO 4 particles were imperfect microcrystals, which stack or compress against each other.

BiVO4 nanoparticles were synthesized through hydrothermal method, and characterized by XRD, SEM, FTIR and UV-Vis. The BiVO4 were pure monoclinic scheelite type, with particle size around...
BiVO4 As a Sustainable and Emerging Photocatalyst: Synthesis ...
Bismuth vanadate (BiVO4) is one of the best bismuth-based semiconducting materials because of its narrow band gap energy, good visible light absorption, unique physical and chemical characteristics, and non-toxic nature.
SEM images for morphology of BiVO4 sample fabricated with …
To develop a highly efficient tungsten-doped BiVO4-based (W-BiVO4) photocatalyst, it is necessary to control the dopant content, crystal structure, and morphology.
An Account on BiVO4 as Photocatalytic Active Matter
2024年3月15日 · Here, we present the synthesis of different BiVO 4 microparticles and their material properties that make them excellent candidates as active micromotors. A critical factor in understanding inherently asymmetric micromotors is knowledge of their flow fields.
Facile and rapid synthesis of a novel spindle-like heterojunction BiVO4 …
2020年1月1日 · Herein, we report pressure-controllable microwave synthesis of a spindle-like monoclinic–tetragonal heterojunction BiVO 4. This synthesis method is facile and fast, only taking about 10 minutes of reaction time, without the addition of organic solvents and surfactants, adjustment of pH and calcination.
Oxygen vacancy induced defect dipoles in BiVO4 for ... - Nature
2024年10月23日 · Here we show that oxygen vacancies in bismuth vanadate (BiVO 4) can create defect dipoles due to a disruption of symmetry. The modified photoelectrodes exhibit a strong correlation between charge...
Mechanism of Charge Separation in Type II Heterostructure: …
5 天之前 · In this study, we explore the photoelectrochemical behavior of planar heterostructured FTO/CuBi2O4/BiVO4 electrode and tandem FTO/BiVO4 || FTO/CuBi2O4 photoelectrochemical cell in order to evaluate the mechanisms of charge separation and transfer in both systems. Both heterostructured and individual electrodes were characterized by SEM, XRD, XPS, and Kelvin …
