A colloidal route to semiconducting tungsten disulfide nanosheets with monolayer thickness

Abstract

Transition metal dichalcogenides (TMDs) are a class of materials that have been extensively studied in the last decade, with molybdenum disulfide (MoS2) being the main protagonist. Typically, the interesting TMD...

Untangling the intertwined: metallic to semiconducting phase transition of colloidal MoS2 nanoplatelets and nanosheets

“…during the synthesis of MoS 2 , WS 2 and MoSe 2 , WSe 2 NSs. 31,32,39,[43][44][45] However, the mechanism by which the individual crystal phases are controlled and formed during the synthesis up to now lacks systematic description. In order to unlock the potential of colloidal synthesis methods for TMDCs we focus on two critical properties of 2D MoS 2 NSs here: the crystal phase and the morphology which we control by vari-…”

Research progress of transition-metal dichalcogenides for the hydrogen evolution reaction

“…Then, the experimental design method was used to simulate the influences of the reaction temperature and precursor injection rate on the colloid synthesis of WS 2 . 58 Among them, the injection rate of the precursor can represent the reaction time, as the injection process encompasses the entire reaction process. It was found that these factors will affect the phase of the product.…”
