Graphene oxide (GO) was used as a smart pH-sensitive carrier for delivery of green corrosion inhibitors to the active corrosion sites of metal. Results demonstrated the physisorption and chemisorption of cerium onto the GO surface. The open circuit potential, polarization test and electrochemical impedance spectroscopy measurements as well as field-emission scanning electron microscopy and energy dispersive spectroscopy were used to study the corrosion inhibition power of GO-Ce system. Results revealed that as a result of cerium oxide hydroxide film generation on the cathodic regions, the corrosion of mild steel was remarkably inhibited in the chloride solution.
