Developing highly-efficient visible-light-driven photocatalyst for water disinfection is an attractive strategy to address the current shortage of safe drinking water and environmental remediation. Since the low dependence on growth substrate and the narrow bandgap nature made ReS 2 one of the best two-dimensional (2D) materials for photocatalytic sterilization. Herein, we fabricated Ag/ReS 2 composite, a 0D/2D heterostructure, which can be grown on three universal substrates through a facile chemical vapor deposition (CVD) and thermal evaporation process. Benefiting from the vertical growth of ReS 2 nanosheets and the hybrid effect from Ag and ReS 2 , the visible-light response of Ag/ReS 2 can be greatly enhanced, exhibiting an excellent photocatalytic antibacterial efficiency towards Escherichia coli ( E. coli ) after 30 min of visible-light exposure, providing a promising environmentally friendly alternative method for water disinfection. Moreover, the universal substrate growth and good stability also endow the photocatalyst with potential applicability in various fields.

Two-dimensional (2D) ReS 2 has received widespread attention because of its unique anisotropic properties, weak interlayer interactions and broad application prospects. Therefore, the controllable and repeatable growth of 2D ReS 2 flakes is very important for studying their properties and practical applications. In this work, 2D single-crystalline ReS 2 flakes with different layer numbers were synthesized on mica substrates using chemical vapor deposition (CVD) by adjusting the distance between the mica substrate and Re source, and the growth mechanism was further discussed. The fluorescence quenching effect and surface-enhanced Raman scattering (SERS) effect of 2D ReS 2 flakes were investigated using rhodamine B (RhB), crystal violet (CV) and malachite green (MG) dye molecules as Raman probes. The results show that the fluorescence quenching effect and SERS effect of 2D ReS 2 flakes are enhanced with decreasing layer number. The lowest detection limits on monolayer ReS 2 flake substrates are 10 −10 M, 10 −9 M and 10 −8 M for RhB, CV and MG under 532 nm laser excitation, respectively. 2D ReS 2 flakes used as a sensitive SERS-active substrate have excellent uniformity and stability. The surface Raman enhancement mechanism of 2D ReS 2 flakes was discussed.

Two-dimensional/one-dimensional (2D/1D) heterostructures have received much attention from researchers for their abundant catalytically active sites and low contact resistance due to formation of chemical bonds at the interface. The investigation of such heterostructures, however, is confined to lattice-matched materials, which severely limits the material candidates. Herein, we demonstrate a lattice-mismatched 2D/1D heterostructured electrocatalyst consisting of 2D ReS2 nanosheets and 1D CoS2 nanowires. We propose that the higher surface energy of the CoS2 nanowire and the lattice mismatch between 1D and 2D units are crucial for the growth process of ReS2 nanosheets. More importantly, the terminal S2– exposed on the surface of CoS2 nanowires serves not only as the nucleus of ReS2 nanosheets but also as a bridge to enhance electron transport efficiency. Thus, the ReS2/CoS2 heterostructures show outstanding hydrogen evolution reaction performance. This work is of general interest for the design of complex multidimensional nano-heterostructures with outstanding functionalities.

Currently, two-dimensional/two-dimensional (2D/2D) van der Waals heterojunctions, as novel and excellent candidates for photocatalysts, have attracted significant attention because of their fundamentally improved interfacial charge separation/transfer and massive reactive centers. Herein, novel 2D/2D Ta 3 N 5 -nanosheet/ReS 2 -nanosheet van der Waals heterojunction photocatalysts are rationally designed through a method combining template-assisted and solution-adsorption processes. The resultant heterojunctions exhibit enhanced interfacial charge transfer, boosted light absorption and significantly increased reaction sites for hydrogen evolution. Correspondingly, they deliver a high photocatalytic hydrogen production activity of 615 μmol g −1 h −1 , which is ∼3 and ∼12 times greater than that of bare Ta 3 N 5 nanosheets and ReS 2 nanosheets, respectively, and superior to those in the most recent reports about photocatalytic water splitting on Ta 3 N 5 material, implying their potential applications as advanced catalysts for hydrogen evolution.

ReS2, as a new member of transition metal dichalcogenides (TMDCs), has emerged as a promising substrate for semiconductor surface-enhanced Raman spectroscopy (SERS) due to its unique optoelectronic properties. Nevertheless, the sensitivity of the ReS2SERS substrate poses a significant challenge to its widespread application in trace detection. In this work, we present a reliable approach for constructing a novel ReS2/AuNPs SERS composite substrate, enabling ultrasensitive detection of trace amounts of organic pesticides. We demonstrate that the porous structures of ReS2nanoflowers can effectively confine the growth of AuNPs. By precisely controlling the size and distribution of AuNPs, numerous efficient and densely packed “hot spots” were created on the surface of ReS2nanoflowers. As a result of the synergistic enhancement of the chemical and electromagnetic mechanisms, the ReS2/AuNPs SERS substrate demonstrates high sensitivity, good reproducibility, and superior stability in detecting typical organic dyes such as rhodamine 6G and crystalline violet. The ReS2/AuNPs SERS substrate shows an ultralow detection limit of 10−10M and a linear detection of organic pesticide molecules within 10−6–10−10M, which is significantly lower than the EU Environmental Protection Agency regulation standards. The strategy of constructing ReS2/AuNPs composites would contribute to the development of highly sensitive and reliable SERS sensing platforms for food safety monitoring.Keywords:ReS2nanoflowers;ReS2/AuNPs complexes;surface-enhanced Raman spectroscopy;quantitative detection

Two-dimensional (2D) lamellar ReS2 nanosheets are considered a promising electrocatalyst for the hydrogen evolution reaction (HER) but suffer from poor intrinsic conductivity and catalytically inert basal planes. In this work, sub 50 nm hierarchical Mo-doped ReS2 nanospheres consisting of numerous few-layered and defect-rich nanosheets are designed and synthesized as robust and efficient HER catalysts. On the one hand, the small size of the hierarchical structure, the disordered basal planes and the expanded interlayer endow the nanosheets with plentiful defects, thereby resulting in abundant exposed active sites. On the other hand, Mo-doping offers the nanosheets with some electronic benefits of unsaturated electrons, improved intrinsic conductivity, and optimized hydrogen adsorption free energy (ΔGH) of the basal planes. Owing to the synergistic effects, the 10%Mo-ReS2 catalyst exhibits an optimized catalytic activity with striking kinetic metrics of a small Tafel slope of 62 mV dec−1, a low overpotential of 81 mV at 10 mA cm−2, and a long operation stability of 50 h, and its performance is among the best of ReS2-based catalysts. This work provides a new approach for gaining the structural and electronic benefits of ReS2 catalysts by combinational nanoscale engineering and heteroatom doping.

Conventional nm-scale Bi 2 O 2 Se-based near-infrared (NIR) photodetectors (PDs) exhibit commendable performance in terms of responsivity and response speed. Currently, the growing complexity of application scenarios requires NIR PDs to possess not only these fundamental functionalities but also the capability for NIR polarization detection and operation well under dim light conditions. Here, this study proposes the 2D ReS 2 /3D Bi 2 O 2 Se homo-heterojunction PD, which exhibits high photo-response speed, polarization-sensitive detection capabilities, and enhanced sensitivity in the NIR spectrum. In detail, a device constructed from µm-thick Bi 2 O 2 Se demonstrates polarization-sensitive photodetection at a wavelength of 850 nm, exhibiting a polarization ratio of 1.4 achieved by applied voltage modulation. Based on photogating effect and strong intrinsic absorption, the homo-heterojunction PD also can detect light power level of nW at 1310 nm, with a response speed of ≈10 µs and responsivity of 34.8 A W −1 at this wavelength. Additionally, this configuration exhibits an outstanding specific detectivity exceeding 10 10 Jones within the wavelength range of 700 to 1310 nm. Even at a cut-off wavelength of 1550 nm, the device achieves a specific detectivity of ≈10 9 Jones. The ReS 2 /Bi 2 O 2 Se heterojunction NIR PD shows promise for advanced optoelectronic applications due to its high sensitivity and polarization-sensitive photodetection in NIR band.

Two-dimensional (2D) rhenium disulfide (ReS2) has been attracting immense interest as a highly promising hydrogen evolution reaction (HER) electrocatalyst recently. However, the HER catalytic active sites of ReS2 are still limited to the finite edges of the nanosheets and the basal-plane is catalytically inert. How to activate the in-plane catalytic activity of ReS2 accordingly becomes the sticking point to further boost its H2 evolution efficiency. Here, the fluorinated ReS2 hierarchical structure assembled as ultrathin nanosheets is proved to exhibit excellent HER activity, where the optimal sample of ReS2-F5.93 shows a low overpotential of 142 mV vs. RHE at a current density of 10 mA cm−2, a Tafel slope of 64 mV dec−1, and significantly improved stability. The enhanced HER performance is mainly attributed to the synergistic effects of increased in-plane active sites and remarkably accelerated charge transfer kinetics. The density functional theory calculation results reveal that F doping can yield the optimal H* adsorption Gibbs free energy and meanwhile increase the electronic states near the Fermi level for accelerated electron transfer. This work can broaden the horizon for designing efficient HER electrocatalysts via activating the in-plane catalytic activity of transition metal dichalcogenides (TMDs).

In this study, we synthesized CdS/(Au–ReS2) nanospheres that have highly efficient photocatalytic hydrogen production activity induced by dielectric–plasmon hybrid antenna resonance. As the diameter (D) of ReS2 nanospheres consisting of 2D nanosheets increases from 114 ± 11 to 218 ± 25 nm, the resonance wavelength of the ReS2 dielectric antenna is tuned from 380 to 620 nm and the hydrogen production rate for the CdS/(Au–ReS2) nanospheres increases by more than 1.85 times and reaches a value as high as 3060 μmol g−1 h−1, with a 9% weight percentage of Au. Due to the enhancements of the local electromagnetic field and excitation energy transfer by the ReS2–Au dielectric–plasmon hybrid antenna, the hydrogen production rate for the CdS/(Au–ReS2) nanospheres (D = 218 ± 25 nm) is 797, 319, 105 and 12 times larger than that for pure ReS2, Au–ReS2, CdS, and CdS–ReS2, respectively. Additionally, the persistence and reusability measurements indicate a favorable stability of CdS/(Au–ReS2). These results provide a strategy to prepare a new class of dielectric–plasmon hybrid antennas consisting of 2D materials and metal nanoparticles, which have promise in applications ranging from photocatalysis to nonlinear optics.

Rhenium (Re)-based transition metal dichalcogenides (TMDs) have excellent in-plane anisotropic optical and electrical properties. However, their distorted octahedral (1T′) structure and weak interlayer coupling easily lead to anisotropic and out-of-plane growth, which makes it particularly difficult to prepare large-area Re-based TMD continuous porous films on SiO2/Si substrates. In this work, ReS2 films are synthesized on SiO2/Si substrates by using tellurium (Te) powder-assisted chemical vapor deposition, and then the films are selenized to synthesize a series of continuous large-area ReS2(1−x)Se2x (x = 0, 0.34, 0.56, 0.84, and 0.91) nanosheet-formed porous films. Furthermore, prototype ReS2(1−x)Se2x photodetectors with different Se compositions are fabricated. The surface morphology, high quality crystallization and compositions are confirmed by various characterization techniques. The ReS2(1−x)Se2x photodetectors based on these films show excellent ultraviolet-visible (UV-vis) spectral responses and self-powered characteristics. The response time is faster, and the photocurrent increases with the Se composition. Due to the Schottky barrier generated by the Ag–ReS2(1−x)Se2x interface, the device without bias voltage has a superior responsivity (121.9 mA W−1), high detectivity (5.27 × 1012 Jones), good on/off ratio (1.2 × 103) and fast response time (rising/decay times, 30/60 ms) under 365 nm light irradiation. This simple and controllable method opens up a new way to produce high-quality vertically oriented ReS2(1−x)Se2x porous arrays on SiO2/Si substrates for next-generation application in UV-vis photodetectors.

Photocatalytic conversion of CO 2 to value-added chemicals and fuels is a green and sustainable approach to solve the problems of CO 2 concentration increment and fossil fuels shortage. Employing photocatalysts with high catalytic activity and selectivity to realize CO 2 conversion has attracted extensive attention. However, the efficiency of photocatalysts is still unsatisfied and the selectivity of products is hard to be regulated, hindering their practical applications in large scale commercial purpose. In this work, for the first time, the Au and Pt was co-deposited on the heterostructure consisted of Cu 2 O quantum dots and ReS 2 nanosheets to achieve high efficiency and controllable selectivity during CO 2 photoreduction. The Au-Pt/Cu 2 O/ReS 2 photocatalysts show superior efficiency of CO 2 reduction than that of Au/Cu 2 O/ReS 2 , Pt/Cu 2 O/ReS 2 , Cu 2 O/ReS 2 , Cu 2 O. Such distinct improvement is attributed to the indirect Z-scheme mechanism and Schottky junction effect. Moreover, the synergetic effect of Au and Pt plays an important role of improving the photocatalytic activity, and the Au1-Pt5/Cu 2 O/ReS 2 exhibits the highest R electron of 516.86 μmol/g during one hour of visible light illumination, which is much larger than many recently reported photocatalysts under comparable condition. Meanwhile, the selectivity of CO and CH 4 is effortlessly tunable from 0 to 100% by modulating Au/Pt metal mass ratio due to the strong CO adsorption on Pt metals and the intensive interaction between Au and Pt atoms at the Au/Pt interface. This controllable selectivity provides admirable strategy to tune the component proportion of the gas products for the subsequent conversion into high value-added chemicals or liquid fuels. Our study proposes novel and deep insights into the design and fabrication of practical photocatalysts with high catalytic activity and controllable selectivity to perform efficient CO 2 photoconversion.

Water purification systems based on transition metal dichalcogenides face significant challenges, including lack of reactivity under dark conditions, scarcity of catalytically active sites, and rapid recombination of photo-generated charge carriers. Simultaneously increasing the number of active sites and improving charge separation efficiency has proven difficult. In this study, we present a novel approach combining molybdenum (Mo) monoatomic doping and size engineering to produce a series of Mo-ReS 2 quantum dots (MR QDs) with controllable dimensions. High-resolution structural characterization, first-principle calculations, and piezo force microscopy reveal that Mo monoatomic doping enhances the lattice asymmetry, thereby improving the piezoelectric properties. The resulting piezoelectric polarization and the generated built-in electric field significantly improve charge separation efficiency, leading to optimized photocatalytic performance. Additionally, the doping strategy increases the number of active sites and improves the adsorption of intermediate radicals, substantially boosting photo-sterilization efficiency. Our results demonstrate the elimination of 99.95% of Escherichia coli and 100.00% of Staphylococcus aureus within 30 min. Furthermore, we developed a self-purification system simulating water drainage, utilizing low-frequency water streams to trigger the piezoelectric behavior of MR QDs, achieving piezoelectric synergistic photodegradation. This innovative approach provides a more environmentally friendly and economical method for water self-purification, paving the way for advanced water treatment technologies. Graphical
