Abstract La‐decorated Bi 2 O CO 3 (BCO‐La) microspheres are synthesized using a facile wet chemical strategy for sensing low‐concentration nonanal (C 9 H 18 O) at room temperature. These BCO‐La gas sensors applied to evaluate agricultural product quality, specifically cooked rice. The sensitivity of the BCO‐6La sensor significantly surpassed that pure BCO sensor, achieving response value 174.6 when detecting 30 ppm gas. Notably, demonstrated faster time (36 s) exposed nonanal. Additionally, selectivity toward detection is higher (approximately 4–24 times) compared interfering gases (1‐octanol, geranyl acetone, linalool, hexanal, 2‐pentyfuran, and 1‐octen‐3‐ol) during rice quality detection. mechanism factors contributing enhanced performance through in situ FT‐IR spectra DFT analysis while realistic scenario carried out. In broader context, reported here represent novel platform monitoring released by products storage.
