چکیده

In this research work, we reported the synthesis of a spherical-shaped bismuth vanadate (BiVO4) photocatalyst using cost-effective, simple, chemical hydrothermal method and studied effect deposition temperatures on structural, morphological, optical properties, etc. The XRD result confirmed monoclinic scheelite phase BiVO4. An XPS study occurrence Bi, V, O elements also found that Bi V exist in +3 +5 oxidation states, respectively. SEM micrographs revealed morphology BiVO4 photocatalyst. Optical investigation showed bandgap varied between 2.25 2.32 eV. as-synthesized was used to photocatalytic degradation crystal violet (CV) dye under visible light illumination. experiment percentage reached 98.21% after 120 min. Mineralization oxygen demand analysis.

A dye-sensitized visible light photocatalyst-Bi24O31Cl10

The p-block semiconductors are regarded as a new family of visible-light photocatalysts because of their dispersive and anisotropic band structures as well as high chemical stability. The bismuth oxide halides belong to this family and have band structures and dispersion relations that can be engineered by modulating the stoichiometry of the halogen elements. Herein, we have developed a new vis...

Visible light-driven CdSe nanotube array photocatalyst

Large-scale CdSe nanotube arrays on indium tin oxide (ITO) glass have been synthesized using ZnO nanorod template. The strong visible light absorption in CdSe, its excellent photoresponse, and the large surface area associated with the tubular morphology lead to good visible light-driven photocatalytic capability of these nanotube arrays. Compared to freestanding nanoparticles, such one-piece n...

Solar synthesis: prospects in visible light photocatalysis.

Chemists have long aspired to synthesize molecules the way that plants do-using sunlight to facilitate the construction of complex molecular architectures. Nevertheless, the use of visible light in photochemical synthesis is fundamentally challenging because organic molecules tend not to interact with the wavelengths of visible light that are most strongly emitted in the solar spectrum. Recent ...
