Heterojunction Engineering of POMOF and ZnO: A Promising Strategy to Boost Triethylamine Gas-Sensing Performance for Fish Freshness Evaluation.
Triethylamine (TEA) serves as a key indicator of fish spoilage, and its accurate detection is essential for assessing fish freshness. However, existing TEA gas sensors often suffer from low sensitivity, sluggish response/recovery kinetics, and high operating temperatures. To address these limitations, this study, for t...
