Abstract
The advance of sensor gas for volatile organic compounds (VOCs) is important for sustainable development of materials science. This project refers to the evaluation of composite based on graphene acid (GA) with oxide metallic (OM) type-n (ex: VO2 and V2O5) and type-p (ex: CoO and Co3O4) and their isolated itself to enhance sensibility and selectivity of gas sensors. The GA (new derivate f…
