A rapid and highly sensitive detection of harmful gas molecules is crucial in artificial olfaction (electronic nose), which plays a significant role areas such as environmental monitoring healthcare. However, it remains challenge to construct molecular sensors with fast response at room temperature due the limitations structures properties (e.g., porosity, crystallinity, carrier mobility) sensing materials. Herein, this study proposes facile method enable crystalline mesoporous WSe2/WO3 (m-WSe2/WO3) semiconductor heterostructures through controllable interfacial self-assembly polyoxometalate (POM) clusters amphiphilic block copolymers combined thermal-assisted conversion process. It allows uniform pore size, open channels, large specific surface area, framework, abundant transition metal chalcogenide/metal oxide heterojunction interfaces. The m-WSe2/WO3-based chemiresistive sensor achieves efficient NO2 temperature, including ultrafast (5 s), high selectivity (SNO2/Sgas > 5), sensitivity (62.5%@50 ppm), low limit (50 ppb), long-term stability (>30 days). Thanks synergistic improvement dynamics between mesostructure heterojunction, few-second time has been reduced by half reported values most existing counterparts based on two-dimensional Our work paves way for application high-performance cost-effective olfaction, electronic skins, wearable integrated circuits temperature.
