Combating marine corrosion on engineered oxide surface by repelling, blocking and capturing Cl−: A mini review

Abstract Cl−-induced corrosion is one ineluctable problem we face when metals and alloys are exposed to marine environment. Herein, we give a mini review covering the aspects of combating Cl−-induced corrosion from the perspective of surface chemistry. Firstly, the interaction of Cl− with oxide surface is briefly reviewed. Then, we highlight some recent strategies for repelling, blocking and capturing Cl− by using surface chemistry control and surface modification via self-assembling at molecular levels.
