J Colloid Interface Sci 2023; 651:805-817. [PMID: 37572616 DOI: 10.1016/j.jcis.2023.08.048] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2023] [Revised: 07/28/2023] [Accepted: 08/07/2023] [Indexed: 08/14/2023]
Abstract
Heterojunctions have been proved to be the promising photocatalysts for hazardous contaminants removal, but the inferior interfacial contact, low carrier mobility and random carrier diffusion seriously hamper the photoactivity improvement of the conventional heterojunctions. Herein, SO chemically bonded p-n oriented heterostructure is fabricated via selectively anchoring of p-type Ag2S nanoparticles on the lateral facet of n-type Bi4TaO8Cl nanosheet. Such a p-n heterojunction engineering on specific facet of Bi4TaO8Cl semiconductor derives ingenious double internal electric field (IEF), which not only effectively creates the spatially separated oxidation and reduction sites, but also delivers the powerful driving forces for impactful spatial directed photocarrier transfer along the cascade path. Additionally, our experimental and theoretical analyses jointly signify that the interfacial SO bond could serve as an efficient atomic-level interfacial channel, which is conducive to encouraging the vectorial charge separation and migration kinetic. As a result, the Ag2S/Bi4TaO8Cl oriented heterojunction exhibits significantly enhanced visible light driven photocatalytic redox ability for tetracycline oxidation and hexavalent chromium reduction than those of single component and the traditional random/mixed heterojunctions. This study could provide a deeper insight into the synergistic effects of multi-IEF modulation and interfacial chemical bond bridging on optimizing the photogenerated carrier behaviors.

SMALL (WEINHEIM AN DER BERGSTRASSE, GERMANY) 2021; 17:e2100320.

Abstract
The severe charge recombination and the sluggish kinetic for oxygen evolution reaction have largely limited the application of hematite (α-Fe2 O3 ) for water splitting. Herein, the construction of Cu2 S/Fe2 O3 heterojunction and discover that the formation of covalent SO bonds between Cu2 S and Fe2 O3 can significantly improve the photoelectrochemical performance and stability for water splitting is reported. Compared with bare Fe2 O3 , the heterostructure of Cu2 S/Fe2 O3 endows the resulting electrode with enhanced charge separation and transfer, extended range for light absorption, and reduced charge recombination rate. Additionally, due to the photothermal properties of Cu2 S, the heterostructure exhibits locally a higher temperature under illumination, profitable for increasing the rate of oxygen evolution reaction. Consequently, the photocurrent density of the heterostructure is enhanced by 177% to be 1.19 mA cm-2 at 1.23 V versus reversible hydrogen electrode. This work may provide guideline for future in the design and fabrication of highly efficient photoelectrodes for various reactions.

Abstract
Infrared spectra of the matrix-isolated Sn(η2 -O2 S), Sn(η2 -OSO), Sn(η2 -O2 S)(η1 -OSO), Sn(η2 -O2 S)2, OSn2 (η2 -SO), and Sn(μ2 -O2 )SnS molecules were observed following laser-ablated Sn atom reactions with SO2 during condensation in solid argon. The assignments for the major vibrational modes were confirmed by appropriate S18 O2 and 34 SO2 isotopic shifts and density functional vibrational frequency calculations (B3LYP and BPW91). Interestingly, the mononuclear complexes are interconvertible; that is, irradiation induces the isomerization of Sn(η2 -O2 S) and Sn(η2 -O2 S)(η1 -OSO) to Sn(η2 -OSO) and Sn(η2 -O2 S)2 , respectively, and vice versa on annealing. However, there is no evidence of isomerization reaction in between the binuclear molecules OSn2 (η2 -SO) and Sn(μ2 -O2 )SnS. Bonding in these products is discussed, and the electronic structure changes associated with different bonding types are revealed, which is crucial for the observed photochemical reactions.
