Modulation of the Surface Catalytic Activity of Boron-Doped Cobalt Oxide with Crystalline/Amorphous Interfaces for High-Stability Acetone Detection.

Enhancing the gas-solid interface interaction between sensing materials and O is promising for the development of high-performance metal oxide-based chemiresistive gas sensors. Nevertheless, high-performance gas sensors have not been developed owing to the lack of a deep understanding of the sensing mechanism with regards to gas-solid interface interactions. In this study, boron-doped cobalt oxide (B-CoO) with crystalline/amorphous interfaces was synthesized for acetone detection.
