High-performance H2S gas sensor utilizing MXene/MoS2 heterostructure synthesized via the Langmuir–Blodgett technique and chemical vapor deposition

An H 2 S gas sensor was developed using an MXene/MoS 2 heterostructure, fabricated through Langmuir–Blodgett and CVD. The gas sensor showed a 5-fold enhancement in gas response for H 2 S, demonstrating a new approach for advanced electronic applications.
