High performance gas sensors based on layered cobaltite nanoflakes with moisture resistance

Facile synthesis of NiFe2O4-based nanoblocks for low-temperature detection of trace n-butanol

“…4 Metal oxide semiconductor (MOS) gas sensors are widely used in industrial applications and household settings because of their benets, including straightforward operation processes and real-time monitoring capabilities. 5 The NiFe 2 O 4 gas sensors have received signicant attention in recent years. The structure exhibits a classic inverse spinel arrangement, with Ni 2+ ions occupying the octahedral site and Fe 3+ ions lling the tetrahedral site.…”
