rGO Loaded Porous NiCo2O4 Nanoplates as Alcohol Gas Sensors
Herein, we report the synthesis of a nickel cobalt oxide nanoplates-reduced graphene oxide sheets (NiCo2O4-rGO) composite by a straight forward strategy. SEM, TEM, XRD and FT-IR were used to characterize the NiCo2O4 nanoplates and the rGO. Attribute to the rGO, the sensitivity of NiCo2O4-rGO sensor as a p-type semiconductor showed 4 times higher than that by NiCo2O4 sensor for alcohol gas at 280 °C and shorten the response/recovery time substantially. Such results mean that the rGO is not only a perfect material for energy application but also available in gas sensing applications.
