Synthesis of BiVO₄ Nanoparticles Using Microwave Process and Their Photocatalytic Activity Under Visible Light
Abstract:
A solvothermal method assisted by microwave technique has been developed for the synthesis of highly crystalline and monoclinic BiVO₄ powders with ellipsoidal structure, using Bi(NO₃)₃ · 5H₂O and Na₃VO₄ · 12H₂O as raw materials, and oleic acid as surfactant. The phase structure and morphology of as-prepared BiVO₄ samples were characterized by XRD, SEM and DRS. We have also investigated the photocatalytic activity of these materials for the decomposition of Rhodamine B under visible light irradiation. From DRS results, BiVO₄ samples showed the absorption spectrum up to the visible region and then their photocatalytic activity was shown higher than commercial P-25 TiO₂ materials. BiVO₄ prepared by the microwave-assisted solvothermal method showed highest photocatalytic activity due to a small particle-size effect.

Dehydration Synthesis
Dehydration synthesis (also called a condensation reaction) is the chemical process in which two molecules covalently link together to form a new molecule, along with the release of a water molecule. Many physiologically important compounds form by dehydration synthesis reactions, such as complex carbohydrates, proteins, DNA, and RNA.

Sugar molecules are covalently linked together by dehydration synthesis. During the reaction, the hydroxyl (-OH) group from...
Transfer RNA Synthesis
Each of these chemical modifications is carried by a specific enzyme, post-transcription. All of these enzymes have unique base and site-specificity. Methylation, the most common chemical modification, is carried by at least nine different enzymes, with...

Photons
A photon is a discrete electromagnetic particle or bundle of energy. Photons are characterized by their frequency, wavelength, and amplitude, similar to the properties of a wave. Waves with higher frequencies transmit more energy and have shorter wavelengths than longer wavelengths that transmit...
Lagging Strand Synthesis
There are several major differences between synthesis of the leading strand and synthesis of the lagging strand. 1) Leading strand synthesis happens in the direction of replication fork opening, whereas lagging strand synthesis happens in the...
