25th Anniversary Article: Hybrid Nanostructures Based on Two‐Dimensional Nanomaterials

Abstract

Two-dimensional (2D) nanomaterials, such as graphene and transition metal dichalcogenides (TMDs), receive a lot of attention, because of their intriguing properties and wide applications in catalysis, energy-storage devices, electronics, optoelectronics, and so on. To further enhance the performance of their application, these 2D nanomaterials are hybridized with other functional nanostructures. In this review, the latest studies of 2D nanomaterial-based hybrid nanostructures are discussed, focusing on their preparation methods, properties, and applications.

Phonon and Raman scattering of two-dimensional transition metal dichalcogenides from monolayer, multilayer to bulk material

“…21(b)) to form various hybrids and heterostructures, creating materials on demand, which will provide fine-tuned properties and new opportunities for devices. [179][180][181] These hybrids and heterostructures are referred to as van der Waals het-erostructures, where strong covalent bonds provide inplane stability of 2D crystals, whereas relatively weak van-der-Waals-like forces are sufficient to keep the stack together.…”

Two-dimensional NiCo2O4nanosheet-coated three-dimensional graphene networks for high-rate, long-cycle-life supercapacitors

“…[38][39][40][41][42][43][44] The high specific surface area of these 2D NS makes them very promising for energy storage applications, especially after they are coated onto 3DGN. As a typical electrode material for pseudocapacitors, NiCo 2 O 4 has been widely investigated in the past few years due to its ultrahigh specific capacitance (over 2000 F g −1 ).…”

Enhanced Catalysis by Optical Nanoantenna Reduced on Transition Metal Dichalcogenide

“…HET, which occurs at interfaces between non-insulating media, e.g., TMD and NA, increases plasmon damping beyond radiative and nonradiative mechanisms [8]. Such damping has been reported to transfer plasmon energy to adjacent 1L semiconducting TMDs [9,10]. Moreover, NP decoration of WS 2 was reported to enhance PL 11-fold via exciton coupling with plasmonic electric near fields [11].…”
