Alloy engineering are efficient methods to improve the physical properties of two‐dimensional (2D) material‐based photovoltaic application. Tin chalcogenide belonging to layered structured semiconducting family has been a significant compound due to its outstanding characteristics. Tin selenide (SnSe) is known as promising layered compound to develop 2D materials for optoelectronic devices. The current study focused onto the effect of tin sulfoselenide (SnSSe) alloy engineering on the structural, morphological, optical, and electrical characteristics. X‐ray Diffraction (XRD) confirmed that SnSSe and SnSe are exist in the orthorhombic crystal structure phase without other secondary phases, with the preferred high‐intensity peak along (111) oriented plane. Raman spectra was reported to give information about the vibrational characteristics of the compounds. The presence of Sulfur ion in SnSSe was further confirmed by Energy Dispersive X‐ray Spectroscopy (EDAX) and X‐ray Photoelectron Spectroscopy (XPS) analysis. Bandgap energy (Eg) has been analysed by Tauc's plot and the derivative of transmittance spectra. According to both sets of analyses, the bandgap of the SnSSe thin film is considerably smaller than that of the SnSe thin film. Hall measurements indicated that SnSSe exhibits the higher hole mobility. The present work‘s results offer useful insight into the prospective device applications of two‐dimensional alloy materials.

“…There are no extra impurity signal peaks appearing in the survey spectrum, indicating the successful synthesis of the nanocomposite after the hydrothermal process. The high-resolution XPS spectrum of Mo 3d (Figure 4b) could be split into two feature peaks, which appeared at ∼232.8 eV and ∼229.6 eV, corresponding to Mo 3d 3/2 and Mo 3d 5/2 [11]. Accordingly, two characteristic peaks in the high-resolution XPS spectrum of S 2p of the MC-4 sample centered at approximately 163.6 eV and 162.6 eV (Figure 4c) correspond to S 2p 1/2 and S 2p 3/2 , respectively [12].…”

“…Co 3 O 4 has been extensively performed in photocatalytic studies attributable to its stupendous benefits such as its low cost, non-toxicity, great quantum efficiency, excellent photosensitivity, and high stability against photo-corrosion. To further enhance the intrinsic activity of MoS 2 , constructing MoS 2 -based nanocomposites can boost the spatial charge separation, improve the active sites, and promote photocatalytic activities [11]. Compared to conventional composites, the nano-heterojunctions formed by the van der Waals force provide a larger surface for the exciton separation, suggesting an outstanding nanocomposite capability and interface quality [12].…”

Photocatalytic hydrogen production joined with simultaneous organic compound removal is a potential but challenging approach for both environmental modification and reusable energy generation. In this study, we designed a nanocomposite method for the fabrication of MoS2/Co3O4 heterojunction with an extremely productive photocatalytic capability. The as-fabricated MoS2/Co3O4 nanocomposites displayed greatly enhanced the hydrogen production (3825 μmol/g/h) and methyl violet dye (MV) contaminant removal (apparent kinetic constant of 0.038 min−1) activity. The nanocomposites’ structures had a better specific surface area, numerous active sites, and enhanced the transport ability of charge carriers to promote the photocatalytic activity. The increase in Co3O4 improved the visible-light absorption efficiency and narrowed energy bandgap and served as a highway for charge carriers to facilitate the transfer and separation and inhibit the combination of photoinduced charge carriers. The migration route of the photoexcited charges, the formation pathway, and the function of various reactive oxygen species (such as O2− and .OH) are discussed. The optimized energy band structure and high electron transfer rate of the S-scheme heterojunction nanocomposite promotes the evolution of H2 and the removal of pollutants, which shows an excellent potential in a stable and efficient photocatalytic hydrogen evolution and environment remediation.

“…Owing to the development of computational science, relevant theoretical calculations and ML technologies can further guide the selection of collaborators and structural design of MoSe 2 -based photocatalysts, [288] helping researchers to further evaluate the potential of MoSe 2 as a cocatalyst. In addition to their use for the photocatalytic HER, numerous modified-MoSe 2 -based Z-scheme photocatalysts have been applied to degrade organic pollutants, [289][290][291][292] and treat wastewater [293,294] by utilizing visible light irradiation, thereby confirming the advantages of employing MoSe 2 -based materials for environmental protection and their considerable commercial potential. , and its relevant photocatalytic behaviors.…”

The development of graphene has readily accelerated the research progress on 2D materials. As a representative 2D family, transition metal dichalcogenides are widely used in the realms of energy storage and conversion. In particular, molybdenum diselenide (MoSe2) has captured widespread interests owing to its unique physical and chemical properties and remarkable potential in energy applications. Nevertheless, typically, the electrochemical property of pristine MoSe2 does not meet the expectations, which necessitates the exploration and applications of proper modification strategies to achieve its full potential. Herein, several state‐of‐the‐art molecular engineering strategies are summarized, and their energy‐oriented applications are described. Furthermore, insightful information on the significance of molecular engineering methods in improving the electrochemical properties of MoSe2 and perspectives on the future developments of MoSe2 are presented. It is anticipated that the research community can use the information in this review to improve the electrochemical properties of MoSe2 targeting practical application scenarios.
