Surface plasmon resonance (SPR) is regarded as a highly encouraging mechanism to enhance the activity of oxygen evolution reaction (OER). Herein, an effective cation exchange strategy is developed for constructing unique Fe2N-embedded mesoporous TiOxNy nanoshells. The TiOxNy nanoshells with high porosity and high electrical conductivity can serve as not only a support to tightly contact the active Fe2N nanoparticles but also a plasmonic material to induce hot electrons for enhancing the OER performance. This work offers a valuable approach for activating the OER electrocatalysis of metal nitrides and can be further extended to metal oxides and hydroxides.
