Bi-2 [a] is a Belarusian alternative rock band, formed in 1988 in Babruysk, Belarusian SSR. During their career, Bi-2 achieved international success in Eastern Europe. [1] [2] [3] Bi-2 was named the Best Rock Act at the MTV Russian Music Awards in 2007.

2024年6月1日 · Compared with other bismuth oxides, BiO 2-x has the following advantages: 1) small band gap (1.5–2 eV) and excellent UV, visible and near-infrared light responsiveness; 2) BiO 2-x itself contains a certain concentration of surface oxygen defects, which can act as a photoinduced electron trapping center and thus inhibit photogenerated carrier ...

2020年8月15日 · Considered that band gap energy (E g) of BiO 2-x is 1.71eV, its conduction band (CB) and valence band (VB) potential can be calculated as −0.46eV and 1.25eV, respectively. Obviously, the band potentials of BiO 2-x and BiOCl take on a staggered band alignment, which contributes to the separation and transfer of photogenerated charge carriers ...

2015年11月12日 · Photocatalysis assessment revealed that Bi 2 O 2 (OH) (NO 3) holds an unprecedented photooxidation ability in contaminant decomposition, far out-performing the well-known photocatalysts BiPO 4, Bi 2 O 2 CO 3, BiOCl and P25 (commercial TiO 2).

2022年1月3日 · Bi2O4/BiO2−x heterojunction could not only raise the charge carriers’ separation efficiency but also broaden the optical absorption range to NIR area. As a result, the optimal Bi2O4/BiO2−x sample exhibits improved visible light photocatalytic degradation activity toward methyl orange (MO) and phenol, which is 2.67-fold and 2.84-fold ...

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 photocurrent measurements.

2023年4月14日 · Piezocatalytic therapy is a new-emerging reactive oxygen species (ROS)-enabled therapeutic strategy that relies on built-in electric field and energy-band bending of piezoelectric materials activated by ultrasound (US) irradiation. Despite becoming a hot topic, material development and mechanism exploration are still underway.

2024年6月3日 · Through hybrid density functional theory calculations and defect analysis, we demonstrate that ABi(III)O 2 (A = Na or K) is a promising wide-band-gap bipolar semiconductor. Our calculations predict A BiO 2 to have a large band gap …

在这种情况下，Bi 的表面等离子共振 (SPR) 效应和 BiO2-x 的氧空位共同提高了污染物的去除率。 更重要的是，Bi/BiO2-x 复合材料在降解 RhB、MO、BPA 和 CIP 以及还原 Cr(VI) 和 PNA 方面具有增强的活性。
