Emerging WS₂/montmorillonite composite nanosheets as an efficient hydrophilic photocatalyst for aqueous phase reactions.

ABSTRACT: Tungsten disulfide (WS₂) as one of transition metal dichalcogenides exhibits excellent catalytic activity. However, its catalytic performances in aqueous phase reactions are limited by its hydrophobicity. Here, the natural hydrophilic two-dimensional clay was used to enhance the dispersibility of WS₂ in aqueous phase. WS₂/montmorillonite (WS₂/MMT) composite nanosheets were prepared via hydrothermal synthesis of WS₂ on the surface of montmorillonite from WCl₆ and CH₃CSNH₂. The microstructure and morphology show that WS₂ nanosheets are assembled parallelly on the montmorillonite with the interface interaction. Through the support of montmorillonite, WS₂/MMT possesses higher photocata
