Abstract The participation of high‐energy hot electrons generated from the non‐radiative decay localized surface plasmons is an important mechanism for promoting catalytic processes. Herein, another vital associated with plasmon resonance (LSPR) effect, significantly contributing to nitrogen reduction reaction (NRR), found. That say, LSPR‐induced strong electric fields can weaken intermolecular hydrogen bonds and regulate arrangement water molecules at solid–liquid interface. AuCu pentacle nanoparticles excellent light absorption ability capability generate are chosen demonstrate this effect. in situ Raman spectra theoretical calculations employed verify molecular scale a fixation process. Meanwhile, due promoted electron transfer interface by well‐ordered interfacial water, as well electrons, optimal catalyst exhibits performance NH 3 yield 52.09 µg h −1 cm −2 Faradaic efficiency (FE) 45.82% ─0.20 V versus RHE. results significant understanding LSPR effect catalysis provide new approach regulating
