Discrimination and detection of NO₂, NH₃ and H₂S using sensor array based on three ambipolar sandwich tetradiazepinoporphyrazinato/phthalocyaninato europium double-decker complexes

Abstract

Developing room-temperature operated gas sensor for highly efficient discrimination of various toxic gases, is highly desirable but remain challenge to date. Herein, a novel sensor array to discriminate the three...

Unveiling the potential of Ti3C2Tx MXene for gas sensing: recent developments and future perspectives

“…1,2 At present, several materials have been investigated and established for gas sensors, such as metal oxides (MO), carbon-based materials, metal-organic frameworks (MOF), conductive polymers, rare-earth oxides, etc. [3][4][5][6][7][8][9][10][11][12] Metal oxide semiconductor (MOS) can be classified into two types, n-type (e.g., ZnO, SnO 2 , TiO 2 , etc.) and p-type (e.g., SnO, CuO, WO 3 , etc.).…”
