Electrochemical degradation of methyl orange on Pt-Bi/C nanostructured electrode by a square-wave potential method

► A novel Pt-Bi/C electrode was prepared with electrochemical deposition. ► Pt-Bi/C electrode was used for MO degradation under a square-wave potential. ► The system exhibited a high MO degradation efficiency. ► An effective electrochemical method was developed for dye wastewater treatment.
