Solution-processed ZnO-chemically converted graphene gas sensor

We report a solution-processed gas sensor based on vertically aligned ZnO nanorods (NRs) on a chemically converted graphene (CCG) film. The prepared sensor device effectively detected 2 ppm of H 2S in oxygen at room temperature. A high sensitivity of the gas sensor resulted from the growth of highly...
