To facilitate the effective monitoring of human health and environmental quality, it is essential to develop high-quality gas sensors for trimethylamine (TEA) with stable sensing sensitivity and low resistance fluctuations in a wide range of humid atmospheres. To this end, a novel Bubble-like Co3O4 tube was fabricated through a ZIF-67 intermediate-assisted thermal decomposition strategy, and its surface morphology and nanostructure were comprehensively investigated. Furthermore, a systematic comparison of the gas sensing properties between Rod-...
