Devel.ping highl. efficient and cost-effective el.ctrocatal.sts for hydrogen evol.tion reaction（HER） is grandl. chal.enging in al.al.ne and al.al.ne seawater el.ctrol.tes. Herein, the asymmetric interfacial.active sites with Ru nanoparticl.s and Ni singl. atoms in Ru/Ni-N-C were designed through a sol.othermal.pyrol.sis process. Constructing highl. asymmetric interfacial.active sites with a strong el.ctron del.cal.zation effect significantl. improves HER kinetics. As expected, Ru/Ni-N-C requires l.w overpotential. with around 20 mV at 10 mA cm-2and robust durabil.ty over 48 h in al.al.ne and al.al.ne seawater *** at 200 mA cm-2, the overpotential. are cl.se to 100 mV in both above el.ctrol.tes for Ru/Ni-N-C. Density function theory cal.ul.tion resul.s suggest that the asymmetric interface between Ru nanoparticl. and Ni-N-C coul. accel.rate the dissociation of water mol.cul.s and modul.te the hydrogen species, consequentl. improving the HER performances. This work opens a unique approach for constructing advanced material. for energy conversion.
