摘      要：Exploring bifunctional electrocatalysts with high-efficiency and stability toward overall water splitting is desirable for sustainable energy technologies,yet ***,we report the construction of Ni_(3)N on the surface of Ni-MOF-74 through an in-situ nitriding *** obtained Ni-MOF-74/Ni_(3)N exhibits remarkable HER activity with an overpotential of 73 mV to deliver 10 mA cm^(-2).Theoretical calculations and experimental study demonstrate the electron transport between Ni_(3)N and Ni-MOF-74,leading to the improved H_(2)O adsorption,optimized hydrogen adsorption,and increased H_(ad)diffusion,which contributes to the enhanced HER ***,the obtained Ni-MOF-74/Ni_(3)N also possesses outstanding activity toward OER and overall water splitting.
