WebbThe gas sensing performance of the cF 3 poPcCo/rGO hybrid gas sensors towards ppb hydrogen sulfide (H 2 S) was measured at room temperature. The results show that the 4-cF 3 poPcCo/rGO sensor has better sensitivity, selectivity and reproducibility than the 3-cF 3 poPcCo/rGO sensor, as well as a perfect linear response to the concentration of H 2 S.
