Rapid and deep self-reconstruction (SELF-RECON) was achieved through rational design of the precatalyst. The obtained core-shell nanowired precatalyst (NiMoFeO@NC) consists of NiMoO4 nanoparticles (core) and NiFe/NiFeOx nanoparticles in N-doped carbons (shell). The SELF-RECON process was facilitated by rapid MoO42− dissolution in the core of NiMoFeO@NC and fast formation of NiOOH with Fe incorporation simultaneously, which was monitored and demonstrated by in situ Raman experiments. The obtained SELF-RECONCAT outperforms NiMoFeO@NC, with ultralow overpotentials and extraordinary long-term stability.Rapid and deep self-reconstruction (SELF-RECON) was achieved through rational design of the precatalyst.
