Enhanced photoelectrochemical water splitting performance of vertically aligned Bi2O3 nanosheet arrays derived from chemical bath deposition method by controlling chemical bath temperature and complexing agent concentration

Tuning the heterophase junction in Bi2O3 hybrid crystals with enhanced photocatalytic activity

“…This surface feature has been observed in chemical bath deposition-derived β-Bi 2 O 3 sheets in which tiny Bi 2 O 3 particles were embedded in the sheet-like crystals. 25 With the prolonged hydrothermal reaction to 9 h, some triangular sheets clump together increasingly, and others shrink and even disappear, as shown in Fig. 2(b).…”

Bismuth-Based Z-Scheme Heterojunction Photocatalysts for Remediation of Contaminated Water

“…ZnO and Bi 2 O 3 are ideal for direct Z-scheme systems because of their position between minimum conduction and maximum valence bands. The chemical bath deposition method is a chemical synthesis technique primarily used to prepare thin films of various materials from aqueous precursor solutions at temperatures below 100 ◦ C. Recently, Sahnesarayi et al prepared a photoelectrode of a Bi 2 O 3 nanosheet using the chemical deposition method …”

Improved performance of UV-blue dual-band Bi2O3/TiO2 photodetectors and application of visible light communication with UV light encryption

“…The morphology and photoelectronic properties of Bi 2 O 3 films prepared by the CBD method depend on the concentration of the precursor solution, pH, deposition temperature, deposition time, category and amount of complexing agent. [27][28][29][30] Triethanolamine (TEA) is the common complexing agent used to deposit Bi 2 O 3 films, which affects the nucleation and growth process: (1) TEA can bind to Bi 3+ to form an unstable Bi-TEA complex, which can reduce the probability of homogeneous nucleation of Bi(OH) 3 from the reaction between Bi 3+ and OH À in the solution for the decreased Bi 3+ amount. (2) TEA can induce the slow release of Bi 3+ from the Bi-TEA complex in the solution during the reaction process, reduce the homogeneous nucleation in solution and promote heterogeneous nucleation of Bi(OH) 3 on the substrates, forming uniform and dense Bi 2 O 3 films on the substrates.…”
