This research demonstrates enhanced H2S detection using Bi2S3/BiOI heterostructures, indicating potential for breath analysis.
Bi 2 S 3 /BiOI heterostructures enable ultrasensitive, low-power, room-temperature H 2 S detection through enhanced interfacial charge transfer, showing strong potential for non-invasive breath analysis of halitosis.
