文摘

We reported Pd@A/nitrogen and sulphur-functionalized multiple graphene aerogel. The nanohybrid offers unique three-dimensional architecture with rich of mesopores. The architecture achieve to ultrahigh electron/ion transfer and electrocatalytic activity. The sensor exhibits an ultrasensitive electrochemical response towards dopamine. The study provides promising approach for the fabrication of graphene-metal hybrids.
