Bi2O3 crystallizes in the cubic Pn-3m space group. The structure is three-dimensional. Bi3+ is bonded in a 6-coordinate geometry to six equivalent O2- atoms. All Bi–O bond lengths are 2.42 Å. O2- is bonded to four equivalent Bi3+ atoms to form …

2024年4月12日 · Calculations of physical properties showed that adding Bi 2 O 3 from 4 to 10 mol% increased the glass density from 2.7878 to 3.3617 g cm −3 and decreased the molar volume from 40.4196 to 38.5895...

2022年6月24日 · Here, we demonstrate that physical manipulation of the grain structure can be used to preserve the superior ionic conductivity of Bi 2 O 3. To investigate the effects of microstructural control...

2024年6月1日 · Bismuth oxide (Bi 2 O 3) stands out for its effective photocatalytic and antibacterial properties. With a moderate band gap, Bi 2 O 3 efficiently absorbs visible light for photocatalysis, generating electron-hole pairs. Its crystal lattice, featuring oxygen vacancies, produces reactive oxygen species (ROS), contributing to antibacterial efficacy.

Bi₂O₃ crystallizes in the cubic Pn̅3m space group. Bi³⁺ is bonded in a 6-coordinate geometry to six equivalent O²⁻ atoms. All Bi-O bond lengths are 2.42 Å. O²⁻ is bonded to four equivalent Bi³⁺ atoms to form a mixture of corner and edge-sharing OBi₄ tetrahedra.

2015年4月13日 · Here, we present a new way to stabilize the δ-Bi 2 O 3 phase to room temperature under oxidizing and reducing conditions by creating layered heterostructures 23 with extremely thin alternating...

2021年6月15日 · Investigations of infrared and Raman spectra reveal that tetrahedral [ZnO 4] and [SiO 4] structural units are main building blocks of glass network, whereas, Bi 2 O 3 exists as both network modifier octahedral [BiO 6] and network former pyramidal [BiO 3] structural units.

In order to overcome it, a potential semiconductor metal oxide, Bismuth (III) Oxide (Bi2O3) with the band gap ranging from 2.1 to 2.8 eV is one of the potential candidates because of its unique characteristics, includ-ing adequately high oxidation power of valence hole (~ + 3.13 V versus normal hydrogen electrode (NHE)) and non-toxic nature as...

In recent years, the semiconductor bismuth oxide (Bi 2 O 3) has attracted increasing attention as a potential visible-light-driven photocatalyst due to its simple composition, relatively narrow bandgap (2.2–2.8 eV), and high oxidation ability with deep valence band levels.

1984年12月1日 · In the present study, in order to elucidate the effect of different heating and cooling processes on phase transitions, we have studied Bi203 by TG-DTA, X-ray diffraction and electron microscopy. New commensurate and incommensurate superstructures of the fluorlte-type have been observed under the electron microscope.
