Webb13 apr. 2024 · The 2p 3/2 peak in the of the Fe/Ni-LDH shifted to 854.77 eV compared with that of Ni-OH, which indicated the high oxidation state of Ni atoms in Fe/Ni-LDH. The both enhancement in the Fe and Ni oxidation state may result from the oxidation process during synthesis and the strong interaction between the Fe and Ni atoms [38]. Webb14 apr. 2024 · We also reveal a strong correlation between the structure and oxidizing power of the Ni in Ni–Fe compounds and their OER activity, indicating that the well-engineered structure and Ni-site electronics are the primary origins of their OER activity.
