Uncovering the photoelectronic/catalytic property modulation and applications of 2D MoS2: from the perspective of constructing heterogeneous interfaces

Abstract

2D polyphase molybdenum disulfide (MoS2) has become a popular material for energy conversion and interdisciplinary applications. Because of the charge transfer (CT) and band bending at the interface, the construction of MoS2 heterostructures (HSs) and heterophases (HPs) may offer new avenues toward the artificial manipulation of carriers, excitons and light at the atomic level, which is key to catalytic/photoelectrical properties. However, few papers have analyzed the carrier dynamics and optical responses of HSs and HPs from the perspective of their composition and interaction effects. Here, we review the ongoing efforts in tailoring the properties of MoS2 in the energy conversion field by forming heterogeneous interfaces. First, the basic knowledge of MoS2 is briefly introduced. Then, recent progress in the design, properties and preparation of MoS2 HSs and HPs is discussed in detail. The design concepts are highlighted from the perspective of band and geometric matching. Emphasis is placed on the component/thickness/stack orientation dependent carrier dynamics and optical responses. Finally, the applications of these materials based on the enhanced catalytic/photoelectronic properties are summarized. We hope that this review will help beginners understand how to effectively customize the physical/chemical properties of MoS2 by carrier modulation and bandgap design, facilitate the development of new and improved MoS2-based structures, and assist in the application of low-dimensional HSs and HPs in more fields.
