Persistent organic pollutants pose significant environmental and health risks, highlighting the urgent need for highly sensitive sensing technologies capable of detecting trace concentrations. In this study, we synthesized a ReS2/ZnO/Au ternary surface-enhanced Raman spectroscopy (SERS) substrate via a simple hydrothermal and reduction method based on a novel strategy that leverages multiple charge transfer channels to significantly enhance SERS performance. The unique bandgap and energy level alignment of ReS2 facilitate both excitonic resonance and charge transfer transitions. Additionally, the semiconductor ZnO acts as an efficient charge transfer mediator by borrowing energy from molecular transitions. As a result of the synergistic combination of electromagnetic and chemical enhancements, the ReS2/ZnO/Au ternary substrate demonstrates excellent versatility and high sensitivity for detecting various pollutants, including rhodamine 6G (R6G), crystal violet, malachite green, and tetracycline (TC). Notably, the detection limit for TC can reach 10–10 M, with an enhancement factor as high as 2.78 × 108. Our strategy provides comprehensive insight into SERS enhancement, offering a pathway for designing sensitive and versatile SERS systems, with significant potential for monitoring and quantitative analysis of organic pollutants.

The dynamic evolution of catalyst structures during the electrocatalytic reaction has seriously hindered our comprehensive understanding of catalytic processes and pathways. In this work, we report that the metal-sulfide (ReS 2 /Co 9 S 8 ) heterostructure has multiple synergistic effects, enhancing the furfural oxidation reaction (FOR) coupling with hydrogen evolution (HER). Under cathodic reduction conditions, H 2 production can be promoted at specific active sites by the original heterostructure of ReS 2 /Co 9 S 8 . Under anodic oxidation conditions, a new heterointerface of ReS 2 /Co 9 S 8 -Co(OH) 2 is in-situ reconstructed based on the original ReS 2 /Co 9 S 8 heterostructure. The new ReS 2 /Co 9 S 8 -Co(OH) 2 heterointerface induced by this ReS 2 /Co 9 S 8 heterostructure significantly enhances FOR performance in an indirect way at 1.33–1.53 V RHE , resulting in a 86.3 % faradaic efficiency (FE). The optimized composite of ReS 2 /Co 9 S 8 with different molar ratios in a two-electrode system exhibits superior performance toward HER||FOR, achieving a smaller cell voltage of 1.43 V to reach 10 mA cm −2 compared to ReS 2 ||Co 9 S 8 (1.69 V). This work verifies the reconstructed heterointerface of ReS 2 /Co 9 S 8 -Co(OH) 2 for FOR and identifies the distinct catalytic mechanisms for FOR and HER.

Elucidation of the photoelectrochemical (PEC) detection mechanism and exploring highly efficient photoactive materials hold both a challenge and an opportunity to construct high-performance biosensors. In this work, we present a strategy to enhance the charge separation efficiency by fabricating hierarchical Ti 3 C 2 @ReS 2 via the vertical anchoring flaky ReS 2 on the Ti 3 C 2 backbone. According to the experimental results, the Ti 3 C 2 @ReS 2 sample containing 45 wt % of ReS 2 exhibits a 2.48-time promotion in the photocurrent as compared to ReS 2 owing to the synergistic effects of its photoactive and conductive counterparts, indicating its significant advantages in separating photo-induced carriers and suppressing carrier recombination. In essence, the Ti 3 C 2 @ReS 2 Schottky junction formed at the interface can capture the photogenerated electrons generated by ReS 2 , thereby suppressing carrier recombination. As a result, an ultrasensitive PEC detection platform based on the optimized Ti 3 C 2 @ReS 2 can offer a log-linear detection window from 0.1 fM to 1 nM with an estimated detection limit of 2.4 aM (S/N = 3) for cancer-related miRNA-141 without any other amplification.

The design of functional materials with efficient light absorption and charge separation is crucial for photocatalytic energy conversion. Herein, a plasmonic TiN/TiO 2 /ReS 2 ternary hybrid is prepared, which exhibits exceptional photocatalytic activity caused by the plasmon-mediated light absorption and multi-interfacial charge separation. The ternary hybrids were synthesized by heating TiN, Re, and S sources at high pressure and temperature. The TiN was partially oxidized to form TiN/TiO 2 hybrids, which were then embedded in ReS 2 nanoflowers through Ti-S bonds, creating a 3D flower-like structure with multiple interfaces. The plasmon resonance of TiN and the bandgap excitations of ReS 2 and TiO 2 endow the hybrids with efficient light absorption in UV–VIS-NIR region. Additionally, the novel embedded structure and the multiple interfaces between TiN, TiO 2 , and ReS 2 facilitate the formation of built-in electric fields and multi-channel charge transfer, which efficiently quicken photoinduced carriers’ migration and hot electron injection. Consequently, the TiN/TiO 2 /ReS 2 hybrids demonstrate a high-efficiency photocatalytic hydrogen generation rate, which is 12.1 times that of commercial P25. Notably, the hybrids also exhibit high photocatalytic activity under near-infrared light irradiation. This study offers innovative insights into the design of photocatalysts and suggests that the prepared materials could be utilized in solar-driven energy conversion applications.

Photoelectrochemical (PEC) water splitting for H2 production is a possible alternative for fossil energy in the future. However, there exists three problems in PEC water splitting with the silicon (Si) photocathode: poor light absorption of the untreated Si substrate, bad stability in strong acid solution, and poor photocatalytic activity of Si. Here, a strategy of dual interface engineering and photocatalyst deposition is proposed to improve the PEC performance, which consists of fabricating black Si (b-Si) by reactive ion etching, depositing of TiO2 on the b-Si by atomic layer deposition, and growing ReS2 on top of the TiO2 by chemical vapor deposition. Owing to the suitable band alignment of b-Si, TiO2, and ReS2, the ReS2/TiO2/b-Si shows obviously enhanced PEC performance compared to b-Si, TiO2/b-Si, and ReS2/b-Si photocathodes. Results of electrochemical impedance spectroscopy and Mott–Schottky plot analysis demonstrate that the TiO2 layer plays an important role and the charge-transfer kinetics of the system is clearly improved. Transient photocurrent measurements indicate that the ReS2/TiO2/b-Si photocathode has the most remarkable photocurrent response. In addition, the ReS2/TiO2/b-Si photocathode also shows excellent stability after being operated for 25 h.

Solar energy is a promising renewable energy with the potential for the sustainable development of the world. Efficient photo-thermal conversion is essential for harvesting and conversion of solar energy, therefore, the main challenge is the development of efficient and low-cost photothermal conversion materials. Carbon framework can be considered as a candidate but somehow its application potential can be still constrained due to the limited absorption of near-infrared (NIR) light. Herein, we propose a general strategy for preparing two-dimensional (2D) transition metal dichalcogenides nanosheets and three-dimensional (3D) carbon framework composites (2D/3D ReS 2 @C) as a photothermal material, which has an excellent broadband light absorption performance (in the wavelength range from 200 to 2500 nm). A small thermoelectric (TE) module with an area of 4 × 4 cm 2 is integrated with annealed ReS 2 @C as a light absorber for the investigation of photo-thermoelectric conversion. The open-circuit voltage of the assembled device increases clearly under solar illumination and reaches the maximum value of 136.3 mV, which is ∼ five times larger than that without the absorber. In addition, 20 TE modules coated with ReS 2 @C absorber layers are connected in series, which can produce a maximum open-circuit voltage of 2.12 V (∼66.25 V/m 2 ) to light up a red light-emitting diode (LED) under natural sunlight. Moreover, the annealed ReS 2 @C powder demonstrates a rapid and strong photothermal response under NIR light (wavelength ＞800 nm), which indicates a great application potential in photothermal imaging and photothermal cancer therapy.

A facile hydrothermal method has been exploited to synthesize the uniform ReS 2 three-dimensional hierarchical nanospheres assembled from few-layered ReS 2 nanosheets with expanded interlayers (designated as porous NSs), resulting in a lot of large pores formed from the curly ReS 2 nanosheets. The expanded interlayers of the ReS 2 porous NSs could accommodate more lithium ions and facilitate lithium ion transports. Especially notable is that the large void spaces in the three-dimensional hierarchical nanospheres is very favorable for buffering the volume expansion, very much favoring the preservation of the electrode integrity during the lithiation/delithiation process. When evaluated as anode materials for lithium-ion batteries at a current density of 100 mA g −1 after 100 cycles, the unique ReS 2 porous NSs deliver a remarkably enhanced reversible capacity of 1011 mAh g −1 with a capacity retention of over 100%, which is significantly superior to the ReS 2 solid microparticles (solid MPs) with a capacity of 458 mAh g −1 and a capacity retention of merely 75%. The very high reversible capacity is indicative of the robustness of the present ReS 2 porous NSs as high-performance anodes for lithium-ion batteries, which may pave the way to further study the three-dimensional self-assembly of two-dimensional layered materials towards the superior electrochemical energy storage.

2D transition metal dichalcogenides materials are explored as potential surface-enhanced Raman spectroscopy substrates. Herein, a systematic study of the Raman enhancement mechanism on distorted 1T (1T′) rhenium disulfide (ReS 2 ) nanosheets is demonstrated. Combined Raman and photoluminescence studies with the introduction of an Al 2 O 3 dielectric layer unambiguously reveal that Raman enhancement on ReS 2 materials is from a charge transfer process rather than from an energy transfer process, and Raman enhancement is inversely proportional while the photoluminescence quenching effect is proportional to the layer number (thickness) of ReS 2 nanosheets. On monolayer ReS 2 film, a strong resonance-enhanced Raman scattering effect dependent on the laser excitation energy is detected, and a detection limit as low as 10 −9 m can be reached from the studied dye molecules such as rhodamine 6G and methylene blue. Such a high enhancement factor achieved through enhanced charge interaction between target molecule and substrate suggests that with careful consideration of the layer-number-dependent feature and excitation-energy-related resonance effect, ReS 2 is a promising Raman enhancement platform for sensing applications.

Improving the electrochemical kinetics and the intrinsic poor conductivity of transition metal dichalcogenide (TMD) electrodes is meaningful for developing next-generation energy storage systems. As one of the most promising TMD anode materials, ReS2 shows attractive performance in potassium-ion batteries (PIBs). To overcome the poor kinetic ion diffusion and limited cycling stability of the ReS2-based electrode, herein, the interlayer distance expanding strategy was employed, and reduced graphene oxide (rGO) was introduced into ReS2. Few-layered ReS2 nanosheets were grown on the surface of the rGO with expanded interlayer distance. The prepared ReS2 nanosheets show an expanded distance (∼0.77 nm). The synthesized EI-ReS2@rGO composites were used in PIBs as anode materials. The K-ion storage mechanism of the ReS2-based anode was investigated by in situ X-ray diffraction (XRD) technology, which shows the intercalation and conversion types. The EI-ReS2@rGO nanocomposites show high specific capacities of 432.5, 316.5, and 241 mAh g–1 under 0.05, 0.2, and 1.0 A g–1 current densities and exhibit excellent reversibility at 1.0 A g–1. Overall, this strategy, which finely tunes the local chemistry and orbital hybridization for high-performance PIBs, will open up a new field for other materials.

Among large numbers of transition metal dichalcogenides (TMDCs), monolayer rhenium disulfide (ReS2) is of particular interest due to its unique structural anisotropy, which opens up unprecedented opportunities in dichroic atomical electronics. Understanding the domain structure and controlling the anisotropic evolution of ReS2 during the growth is considered critical for increasing the domain size toward a large-scale growth of monolayer ReS2. Herein, by employing angle-resolved Raman spectroscopy, we reveal that the hexagonal ReS2 domain is constructed by six well-defined subdomains with each b-axis parallel to the diagonal of the hexagon. By further combining the first-principles calculations and the transmission electron microscopy (TEM) characterization, a dislocation-involved anisotropic evolution is proposed to explain the formation of the domain structures and understand the limitation of the domain size. Based on these findings, growth rates of different crystal planes are well controlled to enlarge the domain size, and moreover, single-crystal domains with a triangle shape are obtained. With the improved domain size, large-scale uniform, strictly monolayer ReS2 films are grown further. Scalable field-effect transistor (FET) arrays are constructed, which show good electrical performances comparable or even superior to that of the single domains reported at room temperature. This work not only sheds light on comprehending the novel growth mechanism of ReS2 but also offers a robust and controllable strategy for the synthesis of large-area and high-quality two-dimensional materials with low structural symmetry.

In this paper, ReS 2 /PANI composites were fabricated using a simple ultrasonic dripping method. A hybrid material was formed through the interaction between the p-type conductive polymer PANI and the n-type ReS 2 . This structure improved the utilization of photogenerated carriers and enhanced the photodetection performance. The ReS 2 /PANI-based PDs exhibited a maximum responsivity of 27 μA/W under simulated light illumination at 0 V bias, with a response time of approximately 0.42 s. The responsivity was approximately one order of magnitude higher than that of PDs constructed with ReS 2 alone, and the response time was reduced from 5 s to 0.42 s. Under illumination with different wavelengths of light, the light absorption was strongest at the ultraviolet wavelength of 365 nm, where a peak responsivity of 60 μA/W was even reached. This work demonstrates the potential of the ReS 2 /PANI heterostructure for developing self-powered photodetectors with promising optoelectronic properties and robust stability, providing a reference for further research in this field.

The electrochemical nitrogen reduction reaction (NRR) offers a sustainable route for ammonia production under ambient conditions, but its efficiency remains limited by sluggish N2 activation and competition from the hydrogen evolution reaction (HER). Rhenium disulfide (ReS2), characterized by weak interlayer coupling and an anisotropic electronic structure, provides a promising platform for nitrogen electrocatalysis; however, the limited abundance and insufficient reactivity of its intrinsic active sites restrict its NRR performance. Here, we introduce a Cr-Vs (sulfur vacancy) pair engineering strategy that transforms the local coordination environment of ReS2 into an electronically differentiated active site. Cr incorporation thermodynamically facilitates the Vs formation, generating a reconstructed Cr-Vs configurations with substantially modified local electronic states. This reconstruction optimizes Re 5d-N 2p orbital hybridization, thereby selectively stabilizing key hydrogenated nitrogen intermediates. Meanwhile, the Cr-Vs pair selectively tunes the competition between NRR and HER, preferentially enhancing the intrinsic NRR activity. Consequently, the optimized RSC-5 catalyst delivers an NH3 yield rate of 67.70 ± 0.72 μg mg-1cat. h-1 and a Faraday efficiency of 10.53 ± 0.38%. This work establishes dopant-vacancy coupling as a generalizable strategy for reconstructing local coordination and decoupling competing reaction pathways, offering design principles for developing selective electrocatalysts for sustainable ammonia synthesis.
