Hydrothermal synthesis of β-bismuth oxide nanowires from particles

Improved photoelectrode performance of chemical solution-derived Bi2O3 crystals via manipulation of crystal characterization

“…7,8 By contrast, a relatively few works on synthesis of b-Bi 2 O 3 crystals are proposed due to the difficulty of synthesizing the metastable bphase. 9 The b-Bi 2 O 3 has a higher photoactivity than a-Bi 2 O 3 because of its lower band gap energy and higher optical absorption in visible light region. 10 Since the b-Bi 2 O 3 phase represents a metastable high temperature modication and is known to transform readily to a-Bi 2 O 3 , controllable synthesis of dened b and a polymorphs and their stabilization at room temperature are complicated.…”

Hydrothermal synthesis, characterization of visible‐light‐driven α‐Bi2O3 enhanced by Pr3+ doping

“…(b),(c),(d)), show that the peak position and shapes of the main band were quite similar to each other. The bands at 591.9 and 631 cm ‐1 in the spectra can easily identify the presence of tetragonal phase in the Pr‐doped samples . The two vibration absorption bands at 475 and 512 cm ‐1 in the spectra could be signed to monoclinic Bi 2 O 3.…”

“…This size (measured by AFM) of the needle shaped Bi 2 O 3 nanoparticles was in good agreement with that calculated using the Scherrer formula (using XRD data). The vibrational bands observed at 844.7, 1392.3 and 3442.3 cm −1 in FTIR spectrum (Figure 2C) were assigned to BiOBi, BiOH and OH stretching modes, respectively 35. TG‐DTA curve of Bi 2 O 3 is shown in Figure 2D.…”
