Phase-Controlled 1T Transition-Metal Dichalcogenide-Based Multidimensional Hybrid Nanostructures

Abstract: Metallic-phase transition-metal dichalcogenides (TMDCs) exhibit unusual physicochemical properties compared with their semiconducting counterparts. However, they are thermodynamically unstable to access and it is even more challenging to construct their metastable-phase heterostructures. Herein, we demonstrate a general solution protocol for phase-controlled synthesis of distorted octahedral 1T WS 2 -based (1T structure denotes an octahedral coordination for W atom) multidimensional hybrid nanostructures from … Show more

“…Hence, the superior HER energetics for the Ag (M)–Co 2 P NHs could be ascribed to the multiple constructed Co 2 P (001)/Ag (111) interfaces, exposing more active sites compared with other counterparts . Moreover, the corresponding calculated charge density distribution (Figure f) indicated that the charge transfer occurred at the heterointerfaces, thus leading to a favorable Co and P electron environment for H* adsorption …”

“…Meanwhile, the Mo 3d spectra (Figure 2f) exhibited shifts of ≈1.2 eV to a lower binding energy compared with MoS 2 NSs (Figure S11, Supporting Information) and ≈0.5 eV for Cd(In)SMoS 2 HNs (Figure S12, Supporting Information). These observed chemical shifts are significant, which may be due not only to the intensive electron transfer at the nanoscale dual‐interfaces, but the entire three counterparts within the one‐dimensional (1D) framework should also be influenced, [ 13 ] thus resulting in continuous electrons transfer from CuInS 2 to Cd(In)S and then to MoS 2 .…”

“…Phase engineering of nanomaterials (PEN), which manipulates the atomic arrangements of nanostructures, is regarded as a facile way to synthesize well-designed nanostructures with novel physicochemical properties and excellent performances in diverse application fields. A phase transition method, one of the most important strategies of PEN, has been extensively applied to obtain nanomaterials with a metastable phase or construct a polymorphic interface. , The amorphous state of nanomaterials that the arrangement of atoms has no long-range order is one of their unique phases and is always caused by the deficient energy for crystallization. ,, At higher annealing temperatures, amorphous nanomaterials can show phase transition from the amorphous to the crystalline or amorphous–crystalline intermediate state. , Meanwhile, chemical transformation induced by the external environment, such as high temperatures, small molecules, metal ions, and pH, due to the thermal and structural instability of the metastable metal chalcogenide nanomaterials is proposed to construct heterostructures that can achieve superior performances compared with their individual components . Thus, combining phase transition and chemical transformation methods to fabricate nanomaterials with a polymorphic interface and heterostructure might achieve superior performance. …”
