Abstract
A simple and reliable ethylene sensor was fabricated based on W-doped Sb2MoO6, which presented excellent responses toward 2-10 ppm ethylene, with high sensitivity, good selectivity, low LOD (24 ppb), excellent repeatability (~100 cycles) and long-term stability (within 45 days). The decreased grain size, abundant defects, proper size mismatch and increased charge separation capability contribute to the enhanced sensing properties. Besides, the sensors were applied in VOCs detection of unhusked rice to demonstrate the practical application potential in rice mildew evaluation.
