Cobalt phthalocyanine (CoPc) has drawn increasing attention in CO₂ electroreduction to CO due to its clear coordination structure (Co–N₄–C) and high selectivity. However, its performance is severely restrained by its poor stability and low conductivity. Herein, a promising catalyst for dispersing CoPc on three-dimensional porous carbon (PC) was prepared via a pyrolysis procedure using NaCl as the template. Benefiting from the high intrinsic activity and large exposure of active sites, as well as the unique carbon architecture with facilitated mass transportation, the derived CoPc/PC catalyst shows impressive performance for CO₂ electroreduction. The CO faradaic efficiency achieves a maximum value of 95% accompanied by a CO partial current density of 20.5 mA cm⁻². The study paves a new avenue for the fabrication of high-efficiency molecular catalysts for CO₂ conversion.

将高度分散的钴酞菁接枝到多孔碳上以实现高效 CO2 电还原的通用途径


钴酞菁（CoPc）由于其清晰的配位结构（Co-N ₄ -C）和高选择性，在 CO ₂ 电还原成 CO 方面受到越来越多的关注。然而，其稳定性差、电导率低，严重制约了其性能的发挥。在此，通过使用 NaCl 作为模板的热解过程制备了一种有前景的用于将 CoPc 分散在三维多孔碳（PC）上的催化剂。得益于高固有活性和大量活性位点暴露，以及具有促进质量传输的独特碳结构，衍生的CoPc/PC催化剂在CO ₂ 电还原方面表现出令人印象深刻的性能。 CO 法拉第效率达到最大值 95%，CO 部分电流密度为 20.5 mA cm ⁻² 。该研究为制备用于CO ₂ 转化的高效分子催化剂开辟了新途径。
