Abstract Intrinsic defect engineering is a powerful tool to tune electronic structures for achieving higher photocatalytic activity. Nevertheless, a more industrialized and controlled defect-engineering approach other than the current complex synthesized route is urgently needed. Herein, a facile and controllable hydrothermal strategy is applied to prepare self-defective SnS2 with the tunable sulfur vacancy and used to remove Cr(VI) for the first time. By various characterization tools, we syste...
Abstract Fabricating 2D/2D heterojunction with vacancy is more favorable to the spatial separation and transfer of charge owing to the matching of unique 2D structure and vacancy engineering, but the regulation and observation of interlayer forces and electronic structure is a challenging task for synthesizing heterojunction photocatalyst and studying the photocatalytic hydrogen evolution mechanism. Herein, an original 2D/2D ZnIn2S4/g-C3N4 Van der Waals heterojunction with S vacancies (ZIS-S/CN ...

Abstract The plasmon-induced interfacial charge-transfer transition (PICTT) involves the direct electron transfer from a plasmonic metal to the acceptor state in a semiconductor (SC). Such plasmonic decay is fostered by strong orbital coupling and mixing of electronic levels in plasmonic metals and SC. Although the effectiveness of PICTT for charge transfer has been testified, its realization still remains a great challenge. Herein, we employed a facile electroless reduction strategy for the in-...

Abstract Herein, two-dimensional (2D) TiO2 mesoporous nanosheets with three to four C3N4 layers grown in situ are employed to design a core–shell 2D/2D van der Waals heterojunction (TiO2/C3N4). Edge-terminated zero-dimensional (0D) Ti3C2 MXene quantum dots (TCQD) are subsequently integrated in the C3N4 surface via electrostatic interactions. The constructed 2D/2D/0D TiO2/C3N4/Ti3C2 composite heterojunction photocatalyst exhibits enhanced CO2 reduction activity compared to TiO2, C3N4, TiO2/C3N4, ...
The vital need for an external dehydrating agent in high-yield production of dimethyl carbonate (DMC) has been circumvented viain situ formation of copper sulfide (Cu2S) bonded 2D-sulfonated organic polymers, Cu-SOPm and Cu-SOPs, by deploying a single-step and solvent-assisted mechanochemical and solvothermal methods, respectively. Cu-SOPm exhibited excellent catalytic activity for the continuous production of DMC from carbon dioxide and methanol without using a dehydrating agent. The presence o...

To explore an efficient electron extraction cocatalyst remains an ongoing task to address the rapid recombination and low transfer rate of electron–hole pairs in photocatalytic water splitting. Herein, it is demonstrated that 2D MXene (Ti3C2) with high electron conductivity can act as an effective electron transfer and transport medium after being hybridized with Ag3PO4, a well-documented photocatalyst for oxygen evolution. The obtained Ag3PO4/MXene photocatalysts exhibit a significantly high ph...
The scalable and high-efficiency production of two-dimensional (2D) materials is a prerequisite to their commercial use. Currently, only graphene and graphene oxide can be produced on a ton scale, and the inability to produce other 2D materials on such a large scale hinders their technological applications. Here we report a grinding exfoliation method that uses micro-particles as force intermediates to resolve applied compressive forces into a multitude of small shear forces, inducing the highly...
Two-dimensional SnS2 nanobelt arrays vertically grown on two-dimensional CuSbS2 nanosheet (2D SnS2⊥2D CuSbS2) heterostructures were synthesized via a facile solution-phase growth route. The resultant SnS2⊥CuSbS2 heterostructures showed enhanced photocatalytic activity for CO2 reduction because of unique structural advantages and the p–n heterojunction with matched energy band alignment.
The mining industry is facing emerging challenges as a result of the increase in energy consumption and environmental demands. These facts have promoted the use of renewable energy sources, such as wind, geothermal and, mainly, solar energy. This paper discusses the role of solar energy (UV-VIS-NIR) in leaching processes, evaluating its potential application in metal extraction from sulfide minerals, based on photochemical mechanisms that promote the regeneration of ferric iron or the so called ...

Over the past few decades, graphitic carbon nitride (g-C3 N4 ) has arisen much attention as a promising candidate for photocatalytic hydrogen evolution reaction (HER) owing to its low cost and visible light response ability. However, the unsatisfied HER performance originated from the strong charge recombination of g-C3 N4 severely inhibits the further large-scale application of g-C3 N4 . In this case, the utilization of cocatalysts is a novel frontline in the g-C3 N4 -based photocatalytic syste...
It is fascinating yet challenging to assemble anisotropic nanowires into ordered architectures of high complexity and intriguing functions. We exploited a facile strategy involving oriented etching of a metal-organic fragment (MOF) to advance the rational design of highly ordered nanostructures. As a proof of concept, a microscale MIL-68(In) single crystal was etched with a K3[Co(CN)6] solution to give a microtube composed of aligned MIL-68(In) nanorods. Annealing such a MIL-68(In) microtube rea...
