The Introduction of Defects in Ti3C2Tx and Ti3C2Tx‐Assisted Reduction of Graphene Oxide for Highly Selective Detection of ppb‐Level NO2

At present, the main gas‐sensing mechanism of oxidized MXene (Ti3C2Tx) is commonly regarded as Schottky barrier modulation, but the influence of surface defects generated by oxidation is ignored and ambiguous. Herein, oxidized Ti3C2Tx crumpled spheres (MS) are obtained, accompanying numerous surface...
