“…Yuan et al synthesized orange-like Bi 2 O 2.33 microspheres via a chemistry precipitation method followed by thermal annealing. 31 Therefore, it is still a challenge that the pure nonstoichiometric phase Bi 2 O 2.33 is directly prepared by a soft chemical method.…”

Bi 2 O 2.33 nanoflowers with pure phase were directly prepared via a solvothermal route. The magnetism behavior of the product was investigated, and the data clearly revealed the room-temperature ferromagnetism of the synthetic sample. This nonstoichiometric bismuth oxide should be the diluted magnetic semiconductors (DMSs). XPS measurements showed that the room-temperature ferromagnetism might be derived from the presence of Bi 2+ in the structure. The achievement of the nonstoichiometric Bi 2 O 2.33 DMSs might pave the way for a new understanding of the underlying ferromagnetic mechanism in DMSs materials.

A simple and low-cost method to fabricate Bi 2 O 3 /active-carbon nanocomposites with high capacitive properties was explored. In particular, the composites synthesized at a bismuth nitrate/active carbon weight ratio of 2:1 exhibited a maximum specific capacitance of 466 F g -1 at a current density of 1 Ag -1 and retained up to 335 F g -1 even at a current density[a] 5751 of 5 A g -1 . In addition, these composites also showed good capacity over 3000 cycles. The excellent electrochemical properties could be due to their high specific surface area, abundant pore volume, and proper loading of Bi 2 O 3 nanospheres.

“…Fang et al [25] generated nonstoichiometric bismuth oxide layers by using the electrochemical corrosion of bismuth foils. Schuisky and Hårsta [26] could produce pure Bi 2 O 2.33 by CVD processes and Huang et al [27] generated Bi 2 O 2.33 particles by wet-chemical processes.…”

In this study, bismuth oxide powder (Bi2O3) was deposited by an atmospheric pressure plasma jet onto borosilicate glass. The layer produced through this method is to be used as a photo catalyst in later applications. The deposited coating was analyzed by X-ray diffraction (XRD) to determine the crystal structure, and X-ray photoelectron spectroscopy (XPS) to analyze the chemical state. The results showed a change in crystal and chemical structure during the deposition process. The morphological properties of the layer were examined with scanning electron microscopy (SEM) and laser scanning microscopy (LSM). The band gap structure of the coating was investigated by UV-Vis spectroscopy. The layer produced by the plasma spraying process consisted of circular multi-phase bismuth oxide droplets (monoclinic Bi2O3 and tetragonal Bi2O2.33), showing a direct band gap of Eg = 2.72 eV, which allows their use as a photocatalyst.
