Nanosheet-to-nanoparticle transformation in charged water microdroplets: a pathway for 2D to 0D materials

Abstract

This study explores the electrospray-induced transformation of molybdenum disulfide (MoS₂), graphene oxide (GO), and tungsten disulphide (WS₂) nanosheets of micrometer lateral dimensions into the respective zero-dimensional nanoparticles within the reactive environment of charged water microdroplets. The products characterized by high-resolution transmission electron microscopy (HRTEM) and Raman spectroscopy showcase charged microdroplets as an ambient, scalable medium for the synthesis of nanomaterials with promising applications in catalysis and environmental remediation.
