Fe incorporation and topochemical oxidative intercalation to form ternary CoNiFe LDHs.

Exfoliation of LDHs into monolayer nanosheets to increase active site exposure.

Main Results:

Optimized Co:Ni ratio in binary hydroxides yielded an overpotential of 339 mV.
Ternary CoNiFe LDHs achieved a reduced overpotential of 280 mV.
Exfoliated monolayer nanosheets further lowered the overpotential to 267 mV.

Conclusions:

Compositional optimization and coordination engineering are effective strategies for enhancing LDH electrocatalysts.
Structural modulation, including exfoliation, significantly boosts catalytic activity.
The developed CoNiFe LDHs show great potential for efficient OER catalysis.
