The construction of active electrocatalysts composed of partially dispersed nanoparticles (NPs) and individual single atomic site with robust thermodynamic stability, has emerged as a viable alternative to benchmark commercial HER electrocatalyst. Herein, a multi-step strategy was designed to synthesize Ru<sub>NP</sub>@Fe<sub>SA</sub>-NC electrocatalyst, and a robust interaction between uniformly dispersed Ru NPs and embedded single-atom Fe sites was uncovered, which not only regulates the particle size of Ru NPs but also controls the spin state and electronic configuration of Fe single atom.

The as obtained electrocatalyst demonstrates a low overpotential of 13 mV at 10 mA cm<sup>−2</sup> in alkaline condition. Remarkably, theoretical calculation indicates that the outstanding performance of Ru<sub>NP</sub>@Fe<sub>SA</sub>-NC stems from the Fe optimized electronic structure of the Ru site, which downshifts the d-band center, reduces the energy barriers for water dissociation and optimizes H* desorption, thereby promoting HER.
