Transition metal dichalcogenides (TMDCs), represented by MX2 (where M = Mo, W and X = S, Se, and Te), and more recently, their moiré superlattices (i.e., formed by superimposing layers of TMDCs with different rotation angles) have attracted considerable interest due to their excellent physical properties and unique nanoscale functionalities. Compared to graphene, the literature indicates that TMDCs offer a competitive advantage in optoelectronic technologies, primarily owing to their compositionally controlled non-zero bandgap. These two-dimensional (2D) nanostructured single or multiple layers exhibit remarkable properties that differ from their bulk counterparts. Moreover, stacking different TMDC monolayers also forms heterostructures and introduces unique quantum effects and extraordinary electronic properties, which is particularly promising for next-generation optoelectronic devices and photo(electro)catalytic applications. Therefore, in this review, we also highlight the new possibilities in the formation of 2D/2D heterostructures of MX2-based materials with moiré patterns and discuss the main critical challenges related to the synthesis and large-scale applications of layered MX2 and MX2-based composites to spur significant advances in emerging optoelectronic and photo(electro)catalytic applications.

By combining binding energy and bond‐charge (BBC) model and density functional theory (DFT) calculations, the electrostatic shielding effects and binding energy shifts of bilayer MoS2, MoSe2, and MoTe2 are studied. In this study, the bilayer MoS2, MoSe2, and MoTe2 had bandgaps of 1.38, 1.28, and 1.01 eV, respectively. It is found that electrostatic shielding by electron exchange is the main cause of density fluctuation and determine the bonding state. We found that the edge polarization exactly vanishes after the bulk phase transition, just as we saw the corner‐localized modes disappear in a system with full open boundaries of bilayer MoTe2. Finally, this study establishes a method for calculating the lattice density with Green's function with energy level shift and provides new methods and ideas for the further study of the electrostatic shielding, bond states and topological phases of nanomaterials.

Molybdenum diselenide (MoSe2), a 2D layered transition metal dichalcogenide, has garnered significant scientific research interest for its catalytic and electrocatalytic activities. Here, a straightforward hydrothermal procedure is used to synthesize MoSe2 nanosheets (NSs) and focus on their adsorption capabilities and hydrogen evolution reaction (HER) activity. The MoSe2 NSs which are synthesized by 12 h of hydrothermal treatment found to exhibit the highest adsorption capacity of 91.67 mg g−1. The kinetics of the adsorption process have been found to follow the pseudo‐second‐order model, signifying chemisorption and multilayer adsorption as described by the Freundlich isotherm. The thermodynamic analysis further suggests that the adsorption proceeds by endothermic and spontaneous mechanisms. The self‐cleaning property of the adsorbent is demonstrated by degrading the dye on the adsorbent‐coated cotton fabric. The sample created using a 12 h hydrothermal method has been shown to have a minimal Tafel slope of 58 mV dec−1. It also shows excellent HER activity at low over‐potential and possesses long‐term durability. The dual functionality of MoSe2 NSs in both adsorption and electrocatalytic activity highlights their potential for application in environmental remediation and renewable energy production.
