2016年12月25日 · The detailed crystal structure of BN-75 °C-5 min, BN-75 °C-6 h, and BN-75 °C-24 h can be further observed by TEM and HRTEM (Fig. 6). The BN-75 °C-5 min sample exhibits fringes with a lattice spacing of 2.744 Å and 3.032 Å, respectively, which can be indexed into the (211) and (012) crystal plane of α-Bi 2 O 3 ( Fig. 6 a, b).

2022年3月8日 · Analysis of the morphology of the fabricated Bi2O3 nanomaterials based on TEM images showed that the obtained ceramic structures could be classified as one-dimensional Bi2O3 nanostructures,...

2016年3月21日 · Characterization results showed that the as-prepared Bi 2 O 3 / (BiO) 2 CO 3 heterojunctions possessed distinct crystal interface and exhibited pronounced structural and optical modulation,...

4 天之前 · The S-scheme Bi2O3/MnS heterojunction is fabricated by loading Bi2O3 onto the MnS surface by solvothermal method. The XRD detection demonstrates that the crystalline structure of MnS remains unaltered after loading Bi2O3. SEM and TEM tests revealed that Bi2O3 is uniformly loaded on the MnS surface and tightly bound to it, forming an S-scheme heterojunction. The heterojunction both boosts the ...

2022年7月1日 · Both scanning electron microscope (SEM) and transmission electron microscope (TEM) found that the particle size of the synthesized Bi 2 O 3 NPs was in the range of 50–100 nm (figure S1). The high-resolution TEM (HRTEM) (figure 1 (b)) gave the information that the 0.28 nm and 0.31 nm interplanar spacings matched with (200) and (111) planes of ...

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.

Due to significant band gap, high refractive index, dielectric permittivity, photoluminescence, dielectric permittivity prominent photoconductivity and photocatalytic activity, preparation of...

2017年3月29日 · 透射电子显微镜 (TEM)、能量色散 X 射线光谱 (EDXS) 和场发射扫描电子显微镜 (FE-SEM) 分析清楚地证实了合成后的 Bi2O3 样品的高纯度和纳米棒形貌。根据 Kubelka-Munk 理论，使用 UV-Vis 漫反射光谱 (UV-Vis DRS) 分析估计 α-Bi2O3 NR 的光学带隙。

Porous β-Bi2O3 nanoplates were firstly synthesized via chemical bath deposition, and showed higher photoinduced current density than nonporous ones though the former possessed larger band gap....

2016年12月25日 · In this study, Z-scheme MIL-53(Fe)/α-Bi 2 O 3 /g-C 3 N 4 photocatalyst was successfully fabricated via an accessible method and comprehensive characterized by XRD, FT-IR, SEM, TEM, XPS, N 2 adsorption-desorption isotherms, UV–vis diffuse reflection spectroscopy and photoelectrochemical analysis.
