The development of graphene promotes the research of similar two-dimensional (2D) materials, especially 2D transition metal dichalcogenides (TMDCs) with semiconductor properties. Monolayer or few-layer TMDCs have several advantages, such as direct band gap, weak interlayer van der Waals force, large interlayer spacing, and abundant marginal active sites, which make them widely used in catalysis, optoelectronics, as well as energy conversion and storage devices. In addition, transition metal diselenides (TMDSs) also possess many intriguing characteristics. For instance, transition metal diselenides (, MoSe) have a more stable 1T phase, larger interlayer spacing, smaller band gap, and more obvious metallic property of Se than TMDCs (, MoS). Thus, it has become one of the most attractive research topics branching out from TMDCs. Herein, this review unveils the structures, synthesis, properties, modifications, applications, and perspectives for TMDSs.
石墨烯的发展推动了类似二维（2D）材料的研究，特别是具有半导体特性的二维过渡金属二硫属化物（TMDCs）。单层或少数层TMDCs具有几个优点，如直接带隙、较弱的层间范德华力、较大的层间距和丰富的边缘活性位点，这使得它们广泛应用于催化、光电子以及能量转换和存储设备。此外，过渡金属二硒化物（TMDSs）也具有许多引人入胜的特性。例如，过渡金属二硒化物（如MoSe₂）具有更稳定的1T相、更大的层间距、更小的带隙以及比TMDCs（如MoS₂）更明显的Se金属特性。因此，它已成为从TMDCs分支出来的最具吸引力的研究课题之一。在此，本综述揭示了TMDSs的结构、合成、性质、改性、应用及前景。
