Mechanism of trace-level detection of dibutyl sulfide (DBS) at room temperature using UV-activated MoO3 coated quartz crystal microbalance (QCM) sensor
Summary
A sputtered MoO3 film on a QCM, lit with ultraviolet light at about 355 nm, detects dibutyl sulfide, a safe stand-in for mustard gas, at room temperature. The sensor gave 0.4 Hz/ppm from 2 to 400 ppm, responded in about 7 s and recovered in about 15 s at 2 ppm, and was selective and reproducible; the paper also discusses the sensing mechanism.
