2021年7月1日 · In this paper, CeVO 4 micro/nano hollow spheres (CVO-HS) composed of closely packed nanoparticles are prepared via a facile critic acid-assisted hydrothermal method. The crystalline phase, composition, structure and morphology of the obtained samples are characterized by several techniques.

2020年12月1日 · X-ray photoelectron spectra (XPS) were obtained by a Phi 5300ESCA system with Mg Kα radiation. FT-IR spectra were investigated using a Bruker Vertex 70 FTIR spectrometer. The microstructure and morphology of the samples were observed by scanning electron microscopy (SEM) (HitachiS-520, JXA-840) …

2024年6月1日 · Visible-light-responsive CeVO 4 /g-C 3 N 4 /LaNiO 3 nanostructure photocatalyst is designed. 1D/0D/1D nanostructure has more active sites and promotes rapid transfer of carriers. Dual Z-scheme heterojunction endues the charge carriers with strong redox ability. Synergies among the designed favorable factors improve the photocatalytic capability.

Compared to pure g-C3N4 catalyst the nanocomposite CeVO4/g-C3N4 shows superior photocatalytic activity in the visible region towards the degradation of ciprofloxacin (CIP) with 92% efficiency ...

In this study, decreased graphene oxide cerium vanadate nanocomposite (CeVO4 /rGO) were synthesized using ammonium metavanadate and cerium (III) nitrate hexahydrate and graphene oxide as...

2023年3月27日 · CeVO4-V2O3 composites were prepared by simple hydrothermal method, and the effects of ethylene glycol(EG) on the products were studied by XRD, N2 adsorption–desorption, SEM, EDS, XPS, PL and UV-vis spectra.

The typical XPS survey spectrum presented in Fig. 2(a) shows peaks that are assigned to Ce4p, C1s, V2p, O1s, and Ce3d. The appearance of C1s peaks might be ascribed to possible carbon adsorption...

The high-resolution XPS spectra (Figure 2j) revealed two distinctive peaks at 904.2 and 900.3 eV, which are associated with the Ce 3d 3/2. Furthermore, two peaks correspond to Ce 3d 5/2 peaks appearing at around 885.9 and 881.8 eV.

2022年2月9日 · Here, based on the good light corrosion resistance and excellent visible light response of Zn 0.5 Cd 0.5 S, as well as the unique catalytic, optical, and electrical properties of CeVO 4, we tightly loaded CeVO 4 on Zn 0.5 Cd 0.5 S by physical coupling to overcome its severe photogenic carrier recombination and obtained a highly efficient photoca...

2024年10月1日 · The chemical states and presence of the elements were investigated using X-ray Photoelectron spectroscopy (XPS). Fig. 10 (a-f) revealed survey spectra and chemical states of the elements present in g-C 3 N 4 /CeVO 4 sample.
