Figure 15. Comparison of OER electrocatalytic performance across different REE types. TM: transition metal; SLD: surface La-defective; NC: nitrogen-doped carbon; LDH: layered double hydroxide; NF: nickel foam; LSFN: La and S co-doped nickel-iron-based multiphase catalyst; OER: oxygen evolution reaction.
