Metal–organic framework-derived trimetallic oxides with dual sensing functions for ethanol

Abstract

Metal-organic framework (MOF) derived metal oxide semiconductors have recently received extensive attention in gas sensing applications due to their high porosity and three-dimensional architectures. Still, challenges remain for MOF-derived materials,...

Preparation of Pt/WO3@ZnO hollow spheres for low-temperature and high-efficiency detection of triethylamine

“…8 Still, they are expensive, complicated to operate, and unable to monitor gas in real-time, 9 which limits their practical application. The creation of metal oxide semiconductor (MOS) gas sensors solves these problems with high integration, low energy consumption, and the advantages for mass production, 10–13 making them the best trade-off in terms of costs or dimensions among all gas sensors.…”

Metal–organic framework-derived metal oxides for resistive gas sensing: a review

“…37–43 This characteristic allows for the precise identification of target gases, increasing their dependability as gas detectors. 44–53 In addition, the large surface area and permeable structure of metal oxides derived from MOFs create a wealth of adsorption sites and pathways, allowing for effective gas–molecule interactions. 54–58 As a consequence, gas detection applications experience enhanced sensitivity and swift response times.…”
