Abstract

The innovation of NO₂ gas sensors is highly desirable in environmental monitoring and human safety. Herein, a macroporous SnO₂/MoS₂ inverse opal hierarchitecture has been constructed with substantial interface charge transfer, which realizes the efficient and stable detection of NO₂ with an enhanced response, fast kinetics, and high selectivity at low temperatures.
