In this review, we present the last ten years of progress in evaluation gas sensing mechanisms. We focus mostly on studies joining theoretical modeling adsorption by density functional theory method with advanced experimental characterization materials. provide background about important aspects that should be taken into account during design effective device and an overview most recently studied materials analytes. Using exemplary works, next show how experiment intertwine revealing mechanism serves to improve performance. end, summarize already made despite existing difficulties, outlook for future methodological development.

With the progression of research on gas sensors, numerous studies are being carried out tuning metal–organic framework (MOF)-derived semiconductor metal oxides (SMOs) for gas-sensing in lieu traditionally synthesized SMOs to attain desired result at lower temperatures and enhance sensor response. Still, no comparative study between MOF-derived has been conducted understand reasons behind such a higher activity. To gain insights into enhanced activity find improved response, was using octahedral Cu-MOF as template fabricate an CuO/NiO (CuO/NiOM) heterostructure (CuO/NiOD) via combustion route. More importantly, our revealed that substitution Ni2+ ions MOF did not destroy porous hierarchical either during calcination process or when were added precursor medium. A surface area (35 m2/g) porosity obtained would have provided sufficient permeability channels sorption NO2 molecules, leading formation maximum concentration active sites. Our results MOF-template-derived CuO/NiOM showed comparatively response S% = 13.9%, with recovery times 18 29 s, respectively, temperature 110 °C compared CuO/NiOD. Further, efficient room-temperature times, p–n heterojunction formed their interface by modifying n-type thermally reduced graphene oxide (rGO) CuO/NiOM. The rGO-CuO/NiOM p-type behavior 23.9% toward 60 ppm room temperature, lowest 10 15 respectively. In addition, also possessed ultralow detection ability up 5 fast recovery.
