Coupling porous Ni doped LaFeO3 nanoparticles with amorphous FeOOH nanosheets yields an interfacial electrocatalyst for electrocatalytic oxygen evolution

The doping of Ni on the LaFeO 3 surface effectively modulates the electronic structure of LaFeO 3 , which enhances the electron transfer between LaFeO 3 and FeOOH, resulting in an enhancement of OER performance.
