Abstract The analysis of exhaled acetone is used as a noninvasive diagnosis for diabetes. Compared with traditional breath tools, chemiresistive gas sensors have attracted more attention real‐time monitoring, owing to the possibility integration and facile operation. However, most reported room‐temperature suffer from complicated preparation, costly raw materials, or relatively long response recovery time. In this work, naturally occurring layered mineral stibnite prepare Sb 2 S 3 by one‐step method electrochemical cathodic exfoliation. As‐prepared displays an amorphous feature porous, hierarchical nanostructure, its formation mechanism rationally proposed. ‐based show excellent sensing performance toward at room temperature, high up 1.46 100 ppm acetone, fast temperature (7 s 30 one response–recovery cycle), which top three shortest times among sensors. exfoliation may offer new strategy preparation discussed devices hold great promise developing cost‐effective high‐performance temperature.
