Abstract The integration of dual-mesoporous structures, the construction heterojunctions, and incorporation highly concentrated oxygen vacancies are pivotal for advancing metal oxide-based gas sensors. Nonetheless, achieving an optimal design that simultaneously combines mesoporous precise heterojunction modulation, controlled through a one-step process remains challenging. This study proposes innovative method fabricating zinc stannate semiconductors featuring structures tunable via direct solution precursor plasma spray technique. As proof concept, resulting stannate-based coatings applied to detect 2-undecanone, key biomarker rice aging. Remarkably, oxide/zinc heterojunctions with well-defined secondary pore structure exhibit exceptional gas-sensing performance 2-undecanone at room temperature. Furthermore, practical experiments indicate developed sensor effectively identifies adulteration in various varieties. These results underscore potential this designing oxides tailored properties high-performance enhanced adsorption capacity features semiconductor make it promising candidate sensing applications agricultural food safety inspections.

Vapor-driven smart materials show significant advantages in areas such as intelligent control, gas detection, and information transmission. However, their typically singular response mechanisms pose challenges for achieving binary behaviors within a single system. Drawing inspiration from bimetallic strips, dual-layer covalent organic framework (DL-COF) membrane is developed with hierarchical pore structure. This exhibits asymmetric expansion or contraction on either side when exposed to morpholine 1,4-dioxane vapors, enabling behaviors. The driving forces underlying these responses are the shifts hydrogen bond equilibrium caused by chain-like bonding swelling effects two layers, which have different degrees of crystallinity. structure further enhances rapid mass transfer, DL-COF achieve an impressive time just 0.6 s. By leveraging its distinct responsiveness can be effectively utilized visual translation encrypted information, reliable decoding gas-encrypted Morse code continuous programmatic vapor inputs.
