Abstract
This study introduces a cutting-edge sensor for nonanal, using a bismuth subcarbonate/copper oxide(Bi₂O₂CO₃/CuO) heterojunction. The sensor exhibits exceptional responsiveness to nonanal concentra-tions from 10-90 ppm, characterized by high sensitivity and excellent linearity. The enhanced sensing performance is attributed to the presence of oxygen vacancies and improved charge separation mech-anisms within the heterojunction. Furthermore, we demonstrate the sensor's practical application in evaluating the quality of cooked rice through the detection of volatile organic compounds (VOCs). This research highlights the potential of this sensor as a valuable tool for agricultural product quality evalua-tion and food safety monitoring.
