2016年12月25日 · In this study, we develop a facile solution crystallization method under mild reaction condition to large-scale synthesis the γ-Bi2 O 3 and α-Bi 2 O 3 through α-Bi 2 O 3 → γ-Bi 2 O 3 → α-Bi 2 O 3 transformation.

2022年3月8日 · Moreover, further analysis of the morphology of the obtained Bi2O3 nanostructures with the use of SEM showed that their diameters ranged from 150 to 500 nm when a calcination temperature of 400...

3 天之前 · The SEM image of bismuth oxide precursor wrapping pollen is shown in Fig. 2 (a). The precursor forms a dense coating layer on the surface of pollen, and the particles are still ellipsoidal and uniform in size. Fig. 2 (b) is a locally enlarged image. It can be seen that the pores originally leading to the interior are uniformly filled with the ...

2021年6月30日 · The morphology of as-fabricated samples was characterized by SEM. Fig. 2 shows typical top-view SEM images of BFO and Bi 2 O 3 /BFO heterojunction films for comparison. As can be seen in Fig. 2 a, BFO film is dense and continuous.

2024年2月26日 · Liquid cell transmission electron microscopy observations first revealed the gradual restructuring of the nanoparticles into nanosheets in the presence of 0.1 M KHCO 3 without an applied potential. Our experiments also associated the restructuring with solubility of bismuth in the electrolyte.

2024年5月17日 · Pure and doped Bi2O3 nanoparticles were synthesized by sol gel method. The synthesized nanoparticles were characterized by X-ray diffraction (XRD), UV-Visible Spectroscopy, SEM (SEM), Thermogravimetry/DTA (TGA/DTA), potentiostat/galvanostat (CV), Electron-spin resonance (ESR) and Fourier transform IR spectroscopy (FTIR).

2024年9月24日 · The effect of the structuring agents on the particle morphology of the synthesized α-Bi 2 O 3 nanoparticles (NPs) was investigated using scanning electron microscopy (SEM). Figure 5a presents the SEM image of α-Bi 2 O …

Scanning electron microscopic (SEM) images depicted highly porous Bi2O3 NPs with little agglomeration. Utilizing diffused reflectance spectra (DRS) data, the energy bandgap ( E g ) value of...

Abstract The pure β-Bi2O3 and fluorine-doped β-Bi2O3 rod-like microstructures were successfully prepared by a facile solid-state chemical reaction process. The composition, structure and morphology of the samples were determined by XRD, EDS, SEM, TEM, HRTEM, XPS and PL. Photocatalytic activities of all samples were investigated via the degradation of methyl orange …
