BiOX/BiOY (X, Y = F, Cl, Br, I) superlattices for visible light photocatalysis applications

Abstract

BiOF/BiOI, BiOCl/BiOBr, BiOCl/BiOI, and BiOBr/BiOI superlattices are suitable for visible light photocatalytic degradation of organic pollutants.

Structure-Dependent Photocatalytic Performance of BiOBrxI1−x Nanoplate Solid Solutions

“…On the other hand, the different energy levels of hybrid orbitals can be formed due to the different molar ratios of Br and I in BiOBr x I 1−x solid solutions, which means that their band structures can be modulated by changing the molar ratio of Br and I. In order to further know the relationship between band structure and photocatalytic activity of BiOBr x I 1−x samples, the energy-level positions of VBM and CBM were calculated by Equations (2) and (3) [51][52][53]:…”

Chloramphenicol Base: A New Privileged Chiral Scaffold in Asymmetric Catalysis

“…In 2016, Chen's group reported [15] a new Ru-chloramphenicol base derivative catalyst 1 d for the asymmetric transfer hydrogenation/dynamic kinetic resolution of N-Boc α-amino-βketoesters 16. This reaction was performed by adding Tween 20 (polysorbate 20) as the phase transfer catalyst in HCOOH-HCOONa buffer.…”

“…The author demonstrated [15] the synthetic utility of this methodology for the stereoselective synthesis of key building block 17 g, which could further be transformed to antibiotic agent vancomycin. Later, this protocol [16] was also successfully extended to the asymmetric synthesis of the broad-spectrum antibacterial drug florfenicol from commercially available 4-(methyl-sulfonyl) benzoic acid (Scheme 11).…”

Enhancement of Fe3O4/Au Composite Nanoparticles Catalyst in Oxidative Degradation of Methyl Orange Based on Synergistic Effect

“…[16] For example, the Fe 3 O 4 /Au NPs have showed excellent catalytic activity and reusability in the reduction of nitroaromatic compounds [17][18][19] or other organic pollutants in the presence of NaBH 4 . [20,21] On the basis of previous studies, it is reasonable to think that Fe 3 O 4 /Au NPs can also provide more catalytically active sites for oxidation simultaneously. [22,23] However, few reports have referred to the study concerning the oxidative degradation of organic dyes catalyzed by Fe 3 O 4 /Au NPs so far.…”
