Nanocomposite materials made of graphene and metal oxides are still a hot topic in the scientific research. The huge potential to tune on-demand the physico-chemical properties of these hybrids made them attractive to different research fields as photovoltaics, energy storage and, of course, chemical sensing. Here, we present the study of a nanocomposite of graphene with SnO2 prepared through a simple one-step synthesis. A chemiresistor device based on this nanocomposite showed interesting sensing features towards CO2 with a linear sensitivity curve in the concentration range 1%-10% of CO2 in dry nitrogen and at room temperature.

Abstract
Nanocomposite materials made of graphene and metal oxides are still a hot topic in the scientific research. The huge potential to tune on-demand the physico-chemical properties of these hybrids made them attractive to different research fields as photovoltaics, energy storage and, of course, chemical sensing. Here, we present the study of a nanocomposite of graphene with SnO2 prepared through a simple one-step synthesis. A chemiresistor device based on this nanocomposite showed interesting sensing features towards CO2 with a linear sensitivity curve in the concentration range 1%-10% of CO2 in dry nitrogen and at room temperature.File in questo prodotto:
