Cyclic Voltammetry Study and Solar Light Assisted Photocatalytic Activity of the CeFeO/CeO/FeO Composite.

The semiconducting nature of CeFeO/CeO/FeO nanocomposite has permitted the degradation of the organic toxic dye methylene blue under the irradiation of ultraviolet and visible light portions of solar radiation. Fullprof-assisted Rietveld refinement analysis, performed using the Match software, has revealed the orthorhombic nature of CeFeO. In addition, in the synthesized material, the cubic phase byproduct CeO was found due to the highly oxidizing nature of the cerium element.

Transient Photocurrent Responses of SrCeTiO Perovskites Under Visible Light Illumination for Photovoltaic Applications.

The objective of this study was to synthesize strontium titanate (SrCeTiO) doped with Ce by solid state method. Its crystalline structure is SrCeTiO, and its bandgap ranges from ~3.3 to ~2.

Enhanced Electrochemical Performance of Highly Porous CeO-Doped Zr Nanoparticles for Supercapacitor Applications.

The aim of this work was to develop an ultrasonic-assisted synthesis method for the fabrication of CeO-doped Zr nanoparticles that would improve the performance of supercapacitor electrodes. This method, which eliminates the need for high-temperature calcination, involves embedding CeO into Zr nanoparticles through 1 hr (CeO-Zr-1) and 2 hrs (CeO-Zr-2) of ultrasonic irradiation, resulting in the formation of nanostructures with significant improvements in their electrochemical properties. Through physicochemical analysis, we observed that the CeO-doped Zr nanoparticles, particularly those treated for 2 hrs (CeO-Zr-2), exhibit superior crystalline phase purity, optimal chemical surface composition, minimal agglomeration with particle sizes below 50 nm, and an impressive average surface area of 178 m/g.

Electrochemical Applications Reveal Enhanced Photocatalytic Performance of TiO-Doped ZnS Nanocomposites.

The titanium dioxide (TiO) nanoparticles were prepared by hydrothermal methods at ambient temperature. Based on XRD analysis, the average crystallite size of pure TiO nanoparticles and those doped with ZnS was calculated to be 58 and 54 nm, respectively. At an angle of 25.

The role of BaTiO nanoparticles as photocatalysts in the synthesis and characterization of novel fruit dyes is investigated.

In the present work, the photocatalytic activity against the natural dye extracted from the novel fruits has been studied by the BaTiO nanoparticles (NPs) under a ultra-violet (UV) light source. The large concentrations of an essential phenolic agent present in this phytochemical extract superimposed with cloths fibers make strong stain and degrade into another form of toxic, which is excluded from the many textiles industries as the colorful waste waters without recycling and removal of that dye pigments have been investigated using both photodegradation and photoluminescence techniques. The entitled nanoparticles (NPs) were prepared using the soft chemical root-modified solvothermal synthesis combo method and exposure to heat treatment such that the annealing process has been done for different temperatures ranging from 100°C to 250°C.
