Abstract
A one-step salt-assisted general synthetic methodology for the controlled phase transformation of various types of 2H-phase transition metal dichalcogenides (2H-TMDs), yielding large-scale metastable 1T'-phase transition metal dichalcogenides (1T′-TMDs), including WS, WSe, MoS, and MoSeis described. By tuning the reaction conditions, alloyed 1T′-TMDs such as WSSeand MoSSeare also obtained. Commercially-available metal salts such as KCO·HO, NaCO, KCO, NaCO, CsCO, RbCO, KHCO, and NaHCO, are demonstrated to be effective for the controlled phase transformation at elevated temperatures in a reducing atmosphere. The technique may be extended to the phase engineering of other materials with various polymorphs.
