The Introduction of Defects in Ti3C2Tx and Ti3C2Tx‐Assisted Reduction of Graphene Oxide for Highly Selective Detection of ppb‐Level NO2 (Adv. Funct. Mater. 15/2022)

Abstract

NO2 Sensing In article number 2108959, Fangmeng Liu, Geyu Lu, and co-workers reveal that Ti atom defects enhance the NO2 sensing properties of oxidized Ti3C2Tx due to the stronger adsorption ability towards NO2, and design Ti3C2Tx/TiO2/rGO crumpled sphere heterostructures to further improve the sensitivity and selectivity of NO2. This work provides a new strategy for enhancing the sensing performance of MXene-based room temperature NO2 sensors.
