Key Points

The study aims to investigate how Co and Fe modifications affect the electronic properties and gas selectivity of WS2 monolayers for NO2 sensing.
Utilized transition metals Co and Fe to modify WS2 monolayers.
Analyzed changes in electronic structure and gas sensing capabilities.
Evaluated gas selectivity specifically for NO2 and H2S.
Co and Fe modifications significantly enhanced the electronic properties of WS2.
The modified WS2 showed improved sensitivity and selectivity for NO2 over H2S.
Optimal modification with Co or Fe led to effective sensing applications in industrial settings.

Implication

Research demonstrates enhanced gas selectivity for NO2 in Co/Fe-modified WS2 monolayers, indicating potential for effective environmental monitoring.

Abstract

Industrial emissions of NO2 and H2S are exacerbating the global environmental crisis. Abundant and cost-effective transition metals Co and Fe can precisely modulate the electronic structure of WS2, enabling efficient...
