Abstract

Hydrogen has been considered as one of the most promising renewable energy for production and storage to replace petroleum-based energy In this study a transition metal carbide was used to replace the platinum electrode We used two-step method to synthesis MoxC-RGO In the first stage Oleylamine (OLA) was used as a solvent to disperse the molybdenum source on graphene oxide (GO) The second stage is high-temperature carbonization treatment The molybdenum precursor is crystallized at a high temperature to form molybdenum carbide and the graphene oxide is reduced at a high temperature to form reduced graphene oxide (RGO) The results show that the Mo2C poder was dispersed in the composite material of RGO The electrochemical results show that the onset potential of MoxC-RGO is about -88mV and the Tafel slope is 67mV dec-1
