## Description

- description: Metal–nitrogen-doped carbon materials (MNCs) exhibit good electrocatalytic
    performance owing to the intrinsic advantages of carbon-based materials and the
    presence of isolated and stabilized metal atoms coordinated by nitrogen sites.
    However, conventional high-temperature pyrolysis of precursor molecules make it
    difficult to control the coordination structure precisely. To address this issue,
    here we report a new synthesis strategy for MNCs. Specifically, we design and
    synthesize Ni-phthalocyanine functionalized with ethynyl groups as solid-state
    thermal polymerization points. After depositing the Ni-phthalocyanine precursor
    on a carbon support and performing a thermal treatment, the resultant carbon composite
    material features a Ni–N₄ coordination structure derived from the precursor, and
    enhanced porosity. This material demonstrates high catalytic activity for the
    CO₂ reduction reaction (CO₂RR). Our synthetic approach is applicable to various
    precursor molecules and carbon supports, paving the way for the further development
    of MNC-based electrode catalysts.
