## Description

- description: Metal–support interaction engineering is considered an efficient strategy
    for optimizing the catalytic activity. Nevertheless, the fine regulation of metal–support
    interactions as well as understanding the corresponding catalytic mechanisms (particularly
    those of non-carbon support-based counterparts) remains challenging. Herein, a
    controllable adsorption–impregnation strategy was proposed for the preparation
    of a porous nonlayered 2D NiO nanoflake support anchored with different forms
    of Pt nanoarchitectures, i.e. single atoms, clusters and nanoparticles. Benefiting
    from the unique porous architecture of NiO nanosheets, abundant active defect
    sites facilitated the immobilization of Pt single atoms onto the NiO crystal,
    resulting in NiO lattice distortion and thus changing the valence state of Pt,
    chemical bonding, and the coordination environment of the metal center. The synergy
    of the porous NiO support and the unexpected Pt single atom–NiO interactions effectively
    accelerated mass transfer and reduced the reaction kinetic barriers, contributing
    to a significantly enhanced mass activity of 5.59 A mgPt−1 at an overpotential
    of 0.274 V toward the electrocatalytic oxygen evolution reaction (OER) while 0.42
    A mgPt−1 at a potential of 0.7 V vs. RHE for the methanol oxidation reaction (MOR)
    in an alkaline system, respectively. This work may offer fundamental guidance
    for developing metal–loaded/dispersed support nanomaterials toward electrocatalysis
    through the fine regulation of metal–support interactions.
