Compared to bulk BiO 2−x, monolayer BiO 2−x has exhibited enhanced photocatalytic performance for rhodamine B and phenol removal under UV, visible, and near-infrared light (NIR) irradiation, which can be attributed to the vacancy V Bi-O ′′′ as confirmed by the positron annihilation spectra.

Jan 30, 2024 · In detail, an unstrained Ca (BiO 2) 2 monolayer not only possesses a suitable band gap value (2.02 eV) to fulfill the photocatalytic water-splitting band edge relationships but also holds favorable transport properties, excellent optical absorption across the visible light spectrum, and spontaneous oxygen production under neutral conditions.

Based on ab initio electronic structure calculations, we have predicted that BiO2 in the metastable b-cristobalite phase is a Dirac semimetal, and that it has three symmetry-related Dirac points at the Fermi energy.

Nov 12, 2015 · In this work, we demonstrate the use of bismuth nitrate Bi 2 O 2 (OH) (NO 3) as an absorbing photocatalyst, which integrates multiple superiorities, like a [Bi 2 O 2] 2+ layered configuration, a non-centrosymmetric (NCS) polar structure and highly reactive {001} facets.

Jun 1, 2024 · Recently, a new type of bismuth oxide, BiO2-x photocatalysts have been extensively exploited for organic pollutant decomposition, CO2 reduction, NO removal and water decomposition due to its mixed valent (Bi 3+ and Bi 5+), layered structure, abundant oxygen vacancies, and narrow bandgap.

BiO2 crystallizes in the orthorhombic Ibam space group. The structure is one-dimensional and consists of four BiO2 ribbons oriented in the (1, 0, 0) direction. Bi is bonded in a 4-coordinate geometry to four O atoms.

Jan 8, 2018 · Herein, a full-spectrum responsive vacancy-rich monolayer BiO 2-x has been synthesized. The increased density of states at the conduction band (CB) minimum in the monolayer BiO 2-x is responsible for the enhanced photon response and photo-absorption, which were confirmed by UV/Vis-NIR diffuse reflectance spectra (DRS) and …

A possible Z-scheme photocatalytic mechanism of β-Bi2O3/ZrO2 heterojunctions based on valence band offset (ΔEVBO) and conduction band offset (ΔECBO) is proposed.
