Summary: Detection of volatile organic compounds (VOCs) in ultra-low concentrations is in high demand in industry and daily life. This study synthesized Co3O4/Ti3C2Tx nanocomposites with a mesoporous structure for ethanol sensing by calcining the precursor of metal-organic frameworks (MOFs) grown on 2D Ti3C2Tx sheets. The resulting sensor showed ultra-high response, fast response/recovery speed, low detection limit, ideal selectivity, and long-term stability, significantly improving ethanol-sensing performance compared to pure Co3O4 and Ti3C2Tx sensors. The formation of a hybrid heterojunction and the presence of 2D Ti3C2Tx nanosheets are crucial factors contributing to the enhanced sensing behaviors. This work opens up a new avenue for developing nanocomposites based on metal oxide and 2D materials for VOCs sensing.

Summary: Heavy metal pollutants are highly toxic and pose great concern in environmental monitoring. Electrochemical detection, hindered by mutual interferences of heavy metal ions, is a main technique with limited sensitivity to Cd2+ ions. This study introduces a metal-free and sustainable nanomaterial, cysteamine covalently functionalized graphene (GSH), which significantly enhances the sensitivity of screen-printed carbon electrode (SPCE) to Cd2+ ions while maintaining sensitivity to other heavy metals. The enhancement is attributed to the grafted thiols on the GSH sheets with strong affinity to Cd2+ ions, based on Pearson's principle. The GSH-modified SPCE also exhibits high reusability and outperforms existing SPCEs modified by non-covalently functionalized graphene derivatives. The GSH-SPCE is successfully validated in tap water.
