“…ReS 2 is an emerging new 2D material, unlike 2H TMDs, crystallizing in 1T′ structure with a triclinic symmetry. [ 23–25 ] This structural feature endows ReS 2 with many novel properties, such as strong in‐plane anisotropic properties and weak interlayer coupling, [ 26–29 ] which bring it tremendous application potential in logic inverters, transistors, polarization‐dependent photodetectors. [ 30–33 ] Different from most 1T′ TMDs which are metastable phase, [ 34 ] the 1T′ ReS 2 is much stable in ambient air and even acid/base.…”

2D transition metal chalcogenides (TMDs) with different compositions, phase structures, and properties offer giant opportunities for building novel 2D lateral heterostructures. However, the studies to date have been largely limited to homophase TMD heterostructures, while the construction of heterophase TMD heterostructures remains a challenge. Herein, the synthesis of 2H-1T′ WS 2 -ReS 2 heterophase junctions with high-quality interface structure via a hydrogen-triggered one-pot growth approach is reported. Sequential introduction of hydrogen during growth system, which acts as a "switch" to selectively turn off the growth of ReS 2 while turning on the growth of WS 2 , allows WS 2 to seamlessly grow around ReS 2 to form the WS 2 -ReS 2 heterojunction. Moreover, WS 2 prefers to nucleate at the vertices of ReS 2 grain with fixed lattice orientation, which makes the surrounding WS 2 grains merge into single crystal. Scanning transmission electron microscopy reveals high crystal quality of the heterojunction with an atomically sharp 2H-1T′ heterophase interface. Transient absorption spectroscopy indicates that the photocarriers can effectively separate at the heterophase interface. Based on the high quality heterophase junction, prominent rectification characteristics and polarization-dependent photodiode properties are achieved. This study provides a robust way for the controlled synthesis of 2D heterophase structures, which is essential for their fundamental studies and device applications.

a viable alternative to more widespread lithium-ion batteries (LIBs). This is because of low cost and ready availability of sodium. [4][5][6] However, the larger ionic radius of Na + (1.02 vs Li + 0.76 Å) leads to sluggish electrochemical kinetics, larger volume change, and unsatisfactory reversibility. Consequently, graphite, the commercial anode material of LIBs, cannot be directly used in SIBs because of suppressed electrochemical kinetics. [7,8] The development of an earth-abundant and low-cost anode material remains a significant research challenge to the fabrication of high-performance SIBs.Recently, transition metal dichalcogenides (TMDs) have attracted attention as potential anode materials for SIBs due to their unique physical and chemical properties. [9][10][11] MoS 2 , a typical TMD, has been widely investigated because of its layered structure with large interlayerspacing (6.15 Å) that is beneficial to insertion/extraction of Na + . [12][13][14] However, conductivity and Na + diffusion is restricted by its semi-conducting 2H-phase and relatively large van der Waals interaction between adjacent layers. This results in poor electrochemical performance. 1T-MoS 2 with metallic conductivity and interlayer-expanded MoS 2 with reduced van der Waals interaction, have therefore been extensively studied. [15][16][17][18] However the fabrication of a stable 1T-MoS 2 together with extremely weak interlayer coupling via a facile and low-cost method has not been reported.Inspiringly, ReS 2 (rhenium disulfide) is a new TMD known to exhibit both distorted 1T (1T′) phase and extremely weak interlayer van der Waals interaction. [19][20][21][22][23] This makes it highly suitable for application to LIBs and SIBs. [24][25][26] The theoretical capacity of ReS 2 is 428 mAh g −1 . This value is based on the conversion reaction between one atom of ReS 2 and four of Li + or Na + . Despite these intrinsic structural advantages, a drawback is that, ReS 2 nanosheets suffer from irreversible structural change on deep charge-discharge processing. Additionally, it is reported that the direction of the largest volume expansion is along the out-of-plane. [27,28] This significantly impedes electrochemical performance of anisotropic ReS 2 anode materials in SIBs. To the best of our knowledge, only limited research has been undertaken to address this, including preparation of ReS 2 (rhenium disulfide) is a new transition-metal dichalcogenide that exhibits 1T′ phase and extremely weak interlayer van der Waals interactions. This makes it promising as an anode material for sodium-ion batteries. However, achieving both a high-rate capability and a long-life has remained a major research challenge. Here, a new composite is reported, in which both are realized for the first time. 1T′-ReS 2 is confined through strong interfacial interaction in a 2D-honeycombed carbon nanosheets that comprise an rGO inter-layer and a N-doped carbon coating-layer (rGO@ReS 2 @N-C). The strong interfacial interaction between carbon and ReS 2 increases overallconduc...

“…[23,43] Due to its low structural symmetry, the vertical growth of ReS 2 is highly spontaneous with appropriate growth conditions. [20,43] And the subsequent growth proceeds along the direction from initial nucleation, leading to vertical separate nanopetals. As the growth time extends, these vertical ReS 2 nanopetals will coalesce to reduce the surface energy and hence, transform into the nanoflower morphology.…”

“…The electrochemical water-splitting through hydrogen evolution reaction (HER) has been considered as a sustainable way for Despite some reports on the HER properties of ReS 2 , it remains challenging to further improve its catalytic performance. [20] First, precise control of the edge sites and elucidating their role in HER has not been realized so far. This is due to that the correlation between the structural evolution and growth process of ReS 2 remains unclear.…”

producing hydrogen, a clean and renewable energy source. [1-7] Platinum (Pt) has been widely recognized as the best HER catalyst, but subject to its high cost and limited storage. Therefore, to replace Pt, many efforts have been devoted to electrocatalysts based on non-noble metals such as transition metal complexes, oxides, phosphide, carbides, and transition metal dichalcogenides (TMDCs). [1-4] Amongst, TMDCs have been widely studied as excellent electrocatalysts for HER. [5-7] TMDCs with the formula MX 2 , where "M" stands for a transition metal and "X" represents a chalcogen, has received extensive attention due to their unique structure and excellent properties in recent years. [8,9] The diverse family of TMDCs offers great opportunities for broad applications, including electronic or optoelectronic devices, sensing, energy storage, and catalysis, to name a few. [10-12] Both theories and experiments have demonstrated that only the edges of most TMDCs are catalytically active, while the basal planes are inert. [5] Therefore, optimizing the edge structures is one of the primary strategies for enhancing HER catalytic activity. [6,7,12] Unlike the well-studied MoW W-, or Hf-based dichalcogenides, [13-17] ReS 2 naturally tends to crystallize in a distorted 1T structure. [18] Due to this distorted T phase structure, the interlayer coupling between ReS 2 layers becomes much weaker. [19] Such weakly interlayer coupling can permit the exposure of more active edge sites, simultaneously facilitating the diffusion of electrolyte ions between layers. [20] Thus, ReS 2 shows great potential as a high-performance HER catalyst. [12,19,21] Since Fujita et al. first reported the high HER activity of the exfoliated ReS 2 , [22] extensive efforts have been devoted to the synthesis of ReS 2 nanostructures for HER. [23-28] One of the primary pathways for synthesizing TMDCs is chemical vapor deposition (CVD), enabling the growth of high-quality, large-area, and atomically thin nanosheets with good uniformity, scalability, and controllability. [29,30] Due to its unique structure, ReS 2 nanosheets can grow perpendicularly to the substrate surface by CVD. [23] Based on this, abundant trions in the two-electron catalytic process can lead to highly efficient hydrogen evolution of ReS 2. [24] Further, the charge regulating effect of TMTM bonds in ReS 2 may offer a new pathway for creating more active states. [25] Rhenium disulfide (ReS 2) has attracted tremendous interests as a promising electrocatalyst for hydrogen evolution reaction (HER) due to its unique distorted 1T structure. However, the controllable synthesis of ReS 2 with desired nanostructures is still a challenge for improving its catalytic performance. Here, ReS 2 nanoflowers are constructed on conductive carbon cloth by means of ambient pressure chemical vapor deposition. Characterization results confirm that the nanoflower structure with enormous edges is attributed to its propensity of out-of-plane growth. To investigate the structure variation of the nanoflowers, systema...
