Adsorption of toxic gases on Graphene/SiO2 and Graphene/h-BN
In this work, the adsorption of gases including five toxic gases CO2, CO, NO, NO2, NH3, and water vapor H2O adopted for hygrometer (humidity sensor) on two constructed heterostructures (G/h-BN and G/SiO2) were investigated on particular sites (Top, Hollow, and Bridge). To fully understand...
