LPG Sensing Application Of Graphene/CeO2 Quantum Dots Composite

Graphene/CeO2 quantum dots (QDs) composite was investigated towards the liquid petroleum gas (LPG) at room temperature. Graphene was synthesized by electrochemical exfoliation of graphite. The composites of graphene/CeO2 QDs was prepared by mixing 20 wt.% of graphene in constant 1g of CeO2. The chemiresistor of 20 wt.% composite possesses optimum value of sensing response and excellent stability.
