将具有高质子导电性的氧化石墨烯（GO）纳米片用于氢的电化学检测。基于附接有Pt/C感测电极和Pt黑参比电极的GO膜的传感器在室温下对空气中ppm浓度的氢显示出良好的电动势（EMF）响应。电动势的变化是高度依赖于类型的传感材料和Pt/C电极在干燥和潮湿的条件下给出了高的传感器响应。大电动势的变化与变化的H2浓度进行了观察，表明有前途的能力，GO的在线监测氢泄漏。
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.
