Zinc stannate microcubes with an integrated microheater for low-temperature NO₂ detection

Abstract

This paper reports a facile technique to construct an oxide nanostructured film on a low-power microheater sensor platform to detect the NO2 gas with high sensitivity and selectivity at a...

Oxygen vacancy-enriched Zn2SnO4 for aliphatic alcohol sensing and enhanced selectivity towards n-butanol

“…Zinc stannate-based chemiresistive sensors are already being studied for the detection of various gases, including carbon monoxide (CO), nitrogen dioxide (NO 2 ), methane (CH 4 ), and volatile organic compounds (VOCs). [21][22][23] Their promising sensitivity, selectivity to few vapours/gases, and ability to operate in harsh environments make them suitable for gas detection and monitoring. Zn 2 SnO 4 has superior electrical conductivity, electron mobility, optical performance, and stability compared to its counterparts ZnO and SnO 2 .…”

Inverse and distorted Co2SnO4 cubic spinel thin films for dimethylamine detection at room temperature

“…26 There is a high priority of research toward stannate-based spinel oxide M 2 SnO 4 (M = Zn, Co, Ba, Mn, Ca, Cd). [27][28][29] From the literature, inverse spinel Co 2 SnO 4 thin films have a narrow bandgap (1.7 eV) and high electron mobility, which is good for forming many oxygen radicals on the surface. This demonstrates that inverse spinel Co 2 SnO 4 is a promising sensing element for gas sensor applications.…”
