Artificial photosynthesis can provide valuable fuels and positively impact greenhouse effects, via transforming carbon dioxide (CO2) and water (H2O) into hydrocarbons using semiconductor‐based photocatalysts. However, the inefficient charge‐carrier dissociation and transportation as well as the lack of surface active sites are two major drawbacks to boosting their activity and selectivity in photocatalytic CO2 reduction. Recently, ReS2 has received tremendous attention in the photocatalysis area due to its intriguing physicochemical properties. Nevertheless, the application of ReS2 in photocatalytic CO2 reduction is scarcely covered. Herein, a heterojunction formed between ReS2 nanosheets and CdS nanoparticles is reported, achieving an apparently raised CO production of 7.1 μmol g−1 and high selectivity of 93.4%. The as‐prepared ReS2/CdS heterojunction exhibits strengthened visible‐light absorption, high‐efficiency electron–hole pair separation/transfer, and increased adsorption/activation/reduction of CO2 on in situ created sulfur vacancies of ReS2, thus all favoring CO2 photoreduction. These are corroborated by advanced characterization techniques, e.g., synchrotron‐based X‐ray absorption near‐edge structure, and density functional theory–based computations. The findings will be of broad interest in practical design and fabrication of surface active sites and semiconductor heterojunctions for applications in catalysis, electronics, and optoelectronics.

properties as well as high activities. [4] However, its catalytic performance does not come up to expectations. In recent years, extensive efforts have been devoted to enhancing the catalytic performance, including decreasing the size, creating defects and doping heteroatoms. [5] Generally, the HER performance mainly relies on the intrinsic properties of catalysts. Therefore, regulating intrinsic electronic/ phase structure seems the effective strategy for highly activity catalyst. [6] To our knowledge, there are two different crystalline phases of MoS 2 based on the various arrangement of the sulphur atom. The common 2H phase (trigonal prismatic structure) possesses semiconductor property with a tunable bandgap between 1.3-1.9 eV, while the 1T phase (octahedral structure) is a metallic conductor with 10 7 times higher electrical conductivity than a 2H phase. [7] Therefore, 1T MoS 2 shows faster electron and charge injection/transfer, leading to superior catalytic activities. Furthermore, owing to the increased active sites on both basal surfaces and edges, 1T MoS 2 exhibits outstanding HER performance. [8] Unfortunately, IT phase cannot be explored from natural mines and it is difficult to get a high-yield production. [9] To date, several strategies have been developed to fabricate metallic-phase MoS 2 , including electron-beam irradiation, [10] chemical alkali metal intercalation, [11] plasma electron transfer, [12] flux method, [13] and phase-controlled synthesis. [14] However, the 1T phase is thermodynamically metastable and can be easily converted into stable 2H MoS 2. [15] Thus, a possible solution to fabricate stable 1T MoS 2 is urgently desired. In recent years, it has been reported that 1 T MoS 2 can be transformed from the 2H phase under the condition of light irradiation, electron beam, metal doping and heterointerface. [16] Particularly, the heterointerface-induced strategy is more desirable to achieve phase conversion owing to the moderate condition and high conversion rate. As we know, heterostructure can trigger a spontaneous electron transfer in the interface, which can tune the electro state of the two contacted components and optimize catalytic activities, leading to high catalytic performance. [17] More specifically, the catalytic activity can also be adjusted by lattice strain engineering and electron injection in the interface. [18] Therefore, heterostructure, with numerous exposed interfaces can not only modify the electro state but also increase the active sites for high-quality HER. However, there still remains a great challenge to fabricate 1T MoS 2 based Metallic phase (1T) MoS 2 has been regarded as an appealing material for hydrogen evolution reaction. In this work, a novel interface-induced strategy is reported to achieve stable and high-percentage 1T MoS 2 through highly active 1T-MoS 2 /CoS 2 hetero-nanostructure. Herein, a large number of heterointerfaces can be obtained by interlinked 1T-MoS 2 and CoS 2 nanosheets in situ grown from the molybdate cobalt oxide nanorod under moderat...

Beyond-lithium-ion batteries are promising candidates for high-energy-density, low-cost and large-scale energy storage applications. However, the main challenge lies in the development of suitable electrode materials. Here, we demonstrate a new type of zero-strain cathode for reversible intercalation of beyond-Li + ions (Na + , K + , Zn 2+ , Al 3+) through interface strain engineering of a 2D multilayered VOPO 4-graphene heterostructure. In-situ characterization and theoretical calculations reveal a reversible intercalation mechanism of cations in the 2D multilayered heterostructure with a negligible volume change. When applied as cathodes in K +-ion batteries, we achieve a high specific capacity of 160 mA h g −1 and a large energy density of~570 W h kg −1 , presenting the best reported performance to date. Moreover, the as-prepared 2D multilayered heterostructure can also be extended as cathodes for highperformance Na + , Zn 2+ , and Al 3+-ion batteries. This work heralds a promising strategy to utilize strain engineering of 2D materials for advanced energy storage applications.
