“…As listed in Table S4, the charge transfer resistances of La 2 O 3 /Ni x P y @NC-1, La 2 O 3 /Ni x P y @NC-2, La 2 O 3 /Ni x P y @NC-3, Ni x P y @NC, La 2 O 3 @NC, RuO 2 , and NF are 1.75, 1.13, 2.05, 1.26, 6.94, 2.96, and 14.7 Ω, respectively. The lower R ct value of the La 2 O 3 /Ni x P y @NC-2 catalyst further indicates that it has faster electron transfer capacity and catalytic kinetics and also confirms the Tafel analysis …”

Exploring non-noble metal electrocatalysts with high activity, elevated stability, and low cost is of great significance for efficient electrochemical energy storage and conversion technologies. Herein, rare-earth metal−organic framework (LaNi-MOF)derived three-dimensional La 2 O 3 /Ni x P y nanoparticles embedded in nitrogen-doped porous carbon (La 2 O 3 /Ni x P y @NC) are rationally synthesized by a facile solvothermal method followed by pyrolysis and a low-temperature phosphating strategy. The highly conductive nitrogen-doped porous carbon and the synergistic effect between La 2 O 3 and Ni x P y nanoparticles provide abundant active catalytic sites and enhance the electron mass transfer capability, which endows the La 2 O 3 /Ni x P y @NC catalyst with excellent oxygen evolution reaction activity. Moreover, the La 2 O 3 /Ni x P y @NC catalyst provides a low overpotential (η 100 = 384 mV), which is superior to that of commercial RuO 2 (η 100 = 451 mV). More importantly, the introduction of La 2 O 3 can not only effectively adjust the electronic structure and morphology of the catalyst but also significantly improve the long-term stability and durability of the La 2 O 3 /Ni x P y @NC electrocatalyst. This work provides an efficient strategy for the future design of highly efficient catalysts enriched with rare-earth species.

“…The oxygen species in carbon materials were mainly divided into O-I (CvO, 530.6/531.1 eV), O-II (C-O, 532.5/532.7 eV) and O-III (O-CvO, 533.9/ 534.3 eV). 41 The small peak with a binding energy of ∼536 eV was attributed to chemisorbed/physisorbed water. The O-I/O-III, which can contribute pseudocapacitance (both in acidic/alkaline electrolyte, Fig.…”
