Abstract
This work reports on the fabrication of a reduced graphene oxide (rGO)/tin oxide (SnO₂) aerogel-basedsensor for the detection of toluene at room temperature. Unlike conventional high-temperature metal oxide gas sensors, this low-power, cost-effective sensor enables efficient toluene detection under am-bient conditions. Our preliminary data clearly show that the rGO/SnO₂ sensor can detect toluene at concentrations as low as 10⁰ parts per billion (ppb); highlighting its potential for the development of practical VOC sensors with enhanced sensitivity.
