## Description

- description: "Electrocatalytic performance of transition-metal layered double hydroxides
    (LDHs) can be substantially enhanced through compositional and structural engineering.
    Herein, ternary (CoNiFe) hydroxide nanocones featuring mixed tetrahedral (Td)
    and octahedral (Oh) coordination are rationally designed to boost oxygen evolution
    reaction (OER) activity. Binary CoNi hydroxide nanocones with mixed coordination
    are first synthesized, among which a Co:Ni ratio of 3:1 exhibits optimal performance
    with an overpotential of 339 mV at 10 mA cm−2. Subsequent Fe incorporation, followed
    by a topochemical oxidative intercalation process, convert the CoNiFe(II) hydroxides
    into CoNiFe(III) LDHs while retaining mixed Td/Oh coordination. Benefiting from
    the synergistic effects of multimetal composition and coordination modulation,
    the resulting\r\nCo3Ni1Fe1 LDH nanocones achieve a markedly reduced overpotential
    of 280 mV. Furthermore, exfoliation into monolayer nanosheets leads to a further
    enhancement in catalytic activity by increasing exposure of accessible active
    sites, ultimately lowering the overpotential to 267 mV. This study highlights
    an effective strategy that integrates compositional optimization, coordination
    engineering, and structural modulation for the development of high-performance
    LDH electrocatalysts."
