(2D) metallic transition metal dichalcogenides
(MTMDCs) have attracted tremendous interest due to their intriguing
physical properties and broad application potential. However, batch
production of high-quality 2D MTMDCs based on existing synthesis on
2D surfaces remains a huge challenge. Herein, a universal synthetic
route for the scalable synthesis of high-quality 2D MTMDC (e.g., TaS2, V5S8, and NbS2) nanosheets
using microcrystalline NaCl crystals as templates via a facile chemical
vapor deposition method is reported. Obviously, this synthetic route
is perfectly compatible with a facile water dissolution–filtration
process for obtaining high-purity MTMDC nanosheet powders. Representatively,
a thickness-uniform 1T-TaS2 nanosheet product can be achieved
that shows unexceptionable dispersibility in ethanol, which allows
its assembly onto arbitrary substrates/electrodes for high-performance
energy-related applications, herein serving as a high-performance
electrocatalyst for the hydrogen evolution reaction. This work sheds
light on the batch production, green transfer, and energy-related
application of 2D MTMDC materials.
