Abstract
Graphene oxide (GO) nanosheets with high protonic conductivity were used for electrochemical detection of hydrogen. The sensor based on a GO membrane attached with a Pt/C sensing electrode and a Pt black reference electrode showed good electromotive force (EMF) response to hydrogen in ppm concentrations in air at room temperature. The EMF changes were highly dependent on type of sensing materials and the Pt/C electrode gave high sensor responses in dry and wet conditions. Large EMF variations with changing H2 concentration were observed, indicating the promising capability of GO for on-line monitoring of hydrogen leakage.
