摘要
Owing to the unique thickness dependent physical and chemical properties,two-dimensional(2D)layered nanomaterials have received tremendous attention and shown great potential in the fabrication of high-performance electronic/optoelectronic devices.Notably,the implication of 2D nanomaterials in the gassensing field has also drawn considerable attention but few related review studies have been reported.This critical review mainly focuses on the current progress of 2D layered nanomaterials in gassensing applications.Firstly,we describe the basic attributes of 2D layered nanostructures and discuss the fundamentals of their gas-sensing applications.Secondly,we have numerated recent gas-sensing studies on typical 2D layered nanomaterials,including graphene,MoS_(2),MoSe_(2),WS_(2),SnS_(2),black phosphorus,and others.Particularly,the optimized strategies for improving their gas-sensing performances are also discussed here.Finally,we conclude this review with some perspectives and the outlook on future advances in this field.
