A two-step gas/liquid strategy for the production of N-doped defect-rich transition metal dichalcogenide nanosheets and their antibacterial applications

A simple two-step strategy based on gas expansion combined liquid exfoliation to synthesize defect-rich N-doped MoS₂ and N-doped WS₂ nanosheets (NSs) was proposed. The NSs with improved peroxidase-like catalytic activity can be applied as effective nanoantimicrobials.
