Reduced graphene oxide with La@Co3O4 and La@CdO nanocomposite based sensors: synthesis, characterization and NO2 sensing properties
In the present study, we report fabrication of La@Co3O4 and La@CdO with rGO as new materials for NO2 sensing at a temperature range of 30–90 °C. The nanocomposites were characterized using various characterization tools like FTIR, Powder XRD and SEM to determine the composition and morphology of the nanocomposite sensors. The sensing properties such as sensor response, response time and recovery time were measured. The obtained results exhibited that rGO/La@Co3O4 showed a response of 2.9 while rGO /La@CdO is 2.4 at 50 °C. The sensor exhibited high selectivity to NO2, which is explained by a higher affinity for NO2 compared to other environmental pollutant gases like Cl2, NO, H2O and CO. The sensing mechanism was explained by the synergistic effect of reduced graphene with La@Co3O4 and La@CdO.
