A 2D/2D/2D Ti3C2Tx@TiO2@MoS2 heterostructure as an ultrafast and high-sensitivity NO2 gas sensor at room-temperature

A 2D/2D/2D Ti 3 C 2 T x @TiO 2 @MoS 2 heterostructure was achieved via a facile one-step hydrothermal strategy; it showed an excellent gas sensing performance to NO 2 , which is mainly attributed to numerous active sites and unique three-phase heterointerfaces.
