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.

Two-dimensional (2D) 2H-1 T′ heterojunctions based on transition-metal dichalcogenides have attracted great attention due to their special interface structures and novel properties. Understanding the growth mechanism and the interface structures is essential for their controllable growth. In this work, we successfully synthesize lateral and vertical MoS 2 /ReS 2 heterojunctions by using a two-step chemical vapor deposition (CVD) method, and deeply explore the evolution of the structure. It is found that the growth mode of heterojunction undergoes a transition from lateral epitaxy to vertical stacking under a high Re/S ratio during the growth. Furthermore, the interface structure is greatly determined by the edge shape of MoS 2 core. Two kinds of structures, with the b-axis of 1 T′ ReS 2 shell parallel to the (1 0 0) and (0 1 0) plane of MoS 2 core respectively, are observed. Meanwhile, by comparing with MoS 2 monolayer, MoS 2 /ReS 2 heterostructures possess a reduced emission intensity due to the carrier transfer. This work provides a robust and controllable strategy for the synthesis of heterostructures with different phase structures.

Visual adaptation allows organisms to accurately perceive the external world even in dramatically changing environments, from dim starlight to bright sunlight. In particular, polarization-sensitive visual adaptation can effectively process the polarized visual information that is ubiquitous in nature. However, such an intriguing characteristic still remains a great challenge in semiconductor devices. Herein, a novel porous metal–organic-framework phototransistor with anisotropic-ReS 2 -based heterojunction is demonstrated for polarization-sensitive visual adaptation emulation. The device exhibits intriguing polarized sensitivity and an adaptive ability due to its strong anisotropic and trapping–detrapping characteristics, respectively. A series of polarization-sensitive neuromorphic behaviors like polarization-perceptual excitatory postsynaptic current, multimode adjustable dichroic ratio and reconfigurable sensory adaption, are experimentally demonstrated through this porous heterojunction phototransistor. More importantly, with the polarization–electricity cooperation strategy, advanced polarization-sensitive visual adaptation with strong bottom-gate control and environment dependence is successfully realized. These results represent a significant step toward the new generation of intelligent visual perception systems in autonomous navigation and human–machine interaction, etc.

Loading 2D layered transition metal dichalcogenides (TMDs) on p-type silicon photocathode is suitable for hydrogen production in solar-driven photoelectrochemical (PEC) water splitting. Similarly, various nanostructured TMDs exposing more active sites are widely explored for improving the PEC performances of composite photoelectrodes. Here, defect engineering using a controllable argon ion beam bombardment is presented on ReS 2 /Si photocathode. The atomic vacancy defects are introduced on the 2D ReS 2 to realize high-density active sites, which significantly enhance the solar-driven hydrogen evolution reaction performance of ReS 2 /Si photocathode. The highest photocurrent density of 18.5 mA cm −2 (at 0 V vs reversible hydrogen electrode) is achieved, under a simulated sun irradiation.

Exploring novel and efficient photocatalysts to accelerate CO 2 photoreduction into useful chemicals or fuels is of great significance. In this work, we developed the three-dimensional (3D) structural heterojunction photocatalysts composed of ReS 2 and Cu 2 O by a drop-casting approach. The ReS 2 microspheres with nanosheets were deposited on the 3D structure of Cu 2 O/Cu foams. The analysis of UV–Vis absorption and PL spectra showed that the ReS 2 @Cu 2 O/Cu heterostructure delivered enhanced visible light absorption and improved charge carrier separation. The resulting ReS 2 @Cu 2 O/Cu-180 exhibited the CO yield of 14.3 µmol g −1 under the visible light irradiation. The realized S-scheme heterostructure not only promoted the separation of the photogenerated electron and hole pairs, but also enhanced the visible light absorption. Furthermore, the enriched electrons with high reducing abilities aggregated into the conduction band and diffused to the surface of Cu 2 O for favoring the CO 2 reduction and CO formation. This study is expected to provide a strategy to prepare high-performance S-scheme photocatalysts to perform efficient photocatalytic CO 2 reduction.

The concentration and type of surface-adsorbed oxygen are critical determinants of gas-sensing performance. Rhenium disulfide (ReS 2 ), a transition metal dichalcogenide (TMD) with a thickness-independent direct bandgap, has garnered considerable attention as a promising material for high-performance gas sensors due to its high carrier mobility and concentration. In this work, an improved rhenium-tellurium eutectic growth method for ReS 2 synthesis is proposed. Furthermore, the type and concentration of surface-adsorbed oxygen on the ReS 2 film were modulated through a combined approach of H 2 annealing and hydrogen peroxide (H 2 O 2 ) solution immersion. This surface modification strategy enabled the fabrication of an ReS 2 -based sensor exhibiting a low detection limit of 0.0219 ppm for hydrogen sulfide (H 2 S) and exceptional resistance to humidity interference, offering a novel route for the design of TMD-based gas sensors.

Early cancer diagnosis is critically enhanced by detecting microRNA (miRNA) biomarkers, such as miRNA-155, whose overexpression correlates with cancer progression. This work presents a highly sensitive photoelectrochemical (PEC) biosensor for miRNA-155 detection leveraging a modified carbon nitride (m-CN) substrate modified by ReS₂ (ReS₂/m-CN), which enhanced electron transfer efficiency and provided abundant sites. The resulting biosensor exhibits exceptional performance with a broad linear detection range from 10 −16 M to 10 −7 M, an ultralow detection limit, high selectivity, and outstanding stability. This work demonstrates the significant potential of the ReS 2 @m-CN-based PEC biosensor for sensitive, cost-effective early cancer diagnostics.

Constructing in-plane heterojunctions with high interfacial density using two-dimensional materials represents a promising yet challenging avenue for enhancing the hydrogen evolution reaction (HER) in water electrolysis. In this work, we report that three-dimensional porous MoS 2 –ReS 2 in-plane heterojunctions, fabricated via chemical vapor deposition, exhibit robust electrocatalytic activity for the water splitting reaction. The optimized MoS 2 –ReS 2 in-plane heterojunction achieves superior HER performance across a wide pH range, requiring an overpotential of only 200 mV to reach a current density of 10 mA cm −2 in alkaline seawater . Thus, it outperforms standalone MoS 2 and ReS 2 . Furthermore, the catalyst exhibits remarkable stability, enduring up to 200 h in alkaline seawater. Experimental results coupled with density functional theory calculations confirm that electron redistribution at the MoS 2 –ReS 2 heterointerface is likely driven by disparities in in-plane work functions between the two phases. This leads to charge accumulation at the interface, thereby enhancing the adsorptive activity of S atoms toward H* intermediates and facilitating the dissociation of water molecules at the interface. This discovery offers valuable insights into the electrocatalytic mechanisms at the interface and provides a roadmap for designing high-performance, earth-abundant HER electrocatalysts suitable for practical applications.

The electrocatalytic hydrogen evolution reaction (HER) in water–alkali and chlor–alkali electrolyzers is an indispensable source of H2 supply for industrial applications. Transition metal dichalcogenides (TMDs) have been demonstrated to be highly promising for the HER, but they are mostly operated in acidic solutions. Rationally designing TMD electrocatalysts towards efficient alkaline HER still remains challenging. Herein, we report a controllable atomic engineering of nitrogen atoms into 1T′-phase ReS2 using a simple one-step method. The optimized material shows a greatly enhanced HER performance under alkaline conditions, achieving a low overpotential of 90 mV at 10 mA cm−2 and outstanding stability (with negligible activity decay during the 140 h test). Density functional theory calculations reveal that rational N-implanting remarkably promotes H2O dissociation and H adsorption/desorption on the edge active sites of ReS2, and meanwhile increases electronic states near the Fermi level for improved charge transfer. Such ensemble effects are proposed to account for the much improved HER activity. The work broadens the horizon for designing TMD materials via atomic-site engineering for alkaline HER or other catalysis reactions.

Binary heterostructures (named as CN@Re) composed of ReS 2 nanospheres and g-C 3 N 4 nanosheets are constructed by electrostatic self-assembly method. The ReS 2 nanospheres were prepared by hydrothermal method and the g-C 3 N 4 nanosheets were treated with surface charge modification. Hydrogen production efficiency of modified CN and CN@Re nanostructures was evaluated in a simulated solar environment. To our surprise, CN5@Re5% exhibits the highest H 2 production up to 1823 μmol g −1 h −1 of CN5@Rey, which is 3.2 times as high as CN. The improvement of the photocatalytic hydrogen production efficiency of modified CN is attributed to its interaction with the hole sacrificing agent lactic acid, while the improvement of the photocatalytic activity of CN@Re nanostructure is attributed to the efficient electron transfer efficiency between CN and ReS 2 and the enhanced light absorption capacity brought by ReS 2 . In addition, the photocatalytic stability of CN5@Re5% has been studied, which can maintain a stable rate of hydrogen production over four cycles. The apparent quantum efficiency is as high as 4.10% at 365 nm and 2.82% at 420 nm.

Current research on rhenium disulfide (ReS2) primarily focuses on small-scale thin sheets, but large-scale two-dimensional (2D) monolayer growth is challenging, with poor photodetector performance. Therefore, an in-depth investigation into the growth process of large-scale ReS2, along with exploring approaches to enhance its optoelectronic performance, will overcome limitations and support scalable production for industrial applications. In this study, we optimized the atmospheric-pressure chemical vapor deposition (APCVD) process to achieve centimeter-scale continuous monolayer ReS2 films. Furthermore, annealing treatment significantly enhances the optoelectronic performance of ReS2, with the annealed ReS2 film-based photodetector exhibiting a responsivity (Rλ) of 0.37 A W−1 and an external quantum efficiency (EQE) of 101.94% under 450 nm illumination, while achieving rapid response and decay times of 2.1 s and 2.0 s, respectively. Remarkably, the ReS2 (annealed)/GaSe van der Waals heterojunction photodetector demonstrates unprecedented performance, exhibiting an ultrahigh Rλ of 48.22 A W−1, an exceptional EQE of 1.33 × 104%, along with a high detectivity of 1.20 × 1012 Jones and an impressive on–off ratio of 4.74 × 103. Meanwhile, it maintains a fast response speed. These findings not only provide new insights into the synthesis of ReS2 but also highlight its great potential for next-generation high-performance optoelectronic devices.

Transition metal dichalcogenides (TMDs) have been widely studied as a promising sulfur host material in Li-S batteries due to their unique physical and chemical properties. Great efforts have been made to prepare carbon/TMDs, especially graphene/TMDs heterostructures as the cathodes of Li-S batteries. Recently, ReS 2 shows a new 1T′ phase and great potential in Li-S batteries because of its stable structure and a large amount of catalytic active sites. Herein, we prepared a new ReS 2 nanosheets anchored on rGO (rGO/1T′-ReS 2 ) composite as a lithium polysulfides (LiPSs) immobilizer and electrocatalyst for Li-S batteries. The unique pore structure and rGO incorporation can effectively mitigate volume expansion and enhance electronical conductivity. Moreover, the novel 1T′ phase of ReS 2 shows both efficient chemical adsorption function and large electrocatalytic active sites of LiPSs . These advantages have been demonstrated by both characterization techniques and theoretical calculations. As a result, the rGO/1T′-ReS 2 /S nanosheets display significantly enhanced coulombic efficiency, rate performance and cycling stability compared with the rGO/S nanosheets and the rGO/1T′-ReS 2 /S nanospheres.
