Supporting materials have a significant impact on heterogeneous molecular catalysts. Herein, we have studied the electrochemical CO₂ reduction on cobalt phthalocyanine (CoPc) with Vulcan XC-72 and carbon nanotubes (CNTs) supports, respectively. Compared with pure CoPc, the resulting CoPc/XC-72 and CoPc/CNTs exhibits a notable improvement in catalytic activity. The CoPc/XC-72 maintains a stable polarization just for 15 h with a turnover number (TON) of 48,600, whereas the CoPc/CNTs lasts over 45 h with a high TON of 180,000 and CO Faraday efficiency of 88%. The excellent catalytic stability of CoPc/CNTs is attributed to a strong π-π interaction between CoPc and CNTs.

载体材料对非均相分子催化剂具有重大影响。在这里，我们研究了分别用Vulcan XC-72和碳纳米管（CNTs）载体在钴酞菁（CoPc）上电化学还原CO _2的方法。与纯CoPc相比，所得的CoPc / XC-72和CoPc / CNT在催化活性方面显示出显着改善。CoPc / XC-72仅在15小时内保持稳定的极化状态，周转数（TON）为48,600，而CoPc / CNTs持续45 h以上，TON值为18万，CO法拉第效率为88％。CoPc / CNT的出色催化稳定性归因于CoPc和CNT之间的强π-π相互作用。
