“…40 Representative examples include CoPc and NiPc, which are extensively investigated as catalysts for electrochemical CO 2 R. Notably, CoPc-based electrocatalysts stand out with their high activity and selectivity, 41,42 arising from their facile availability, chemical durability, and tunability at the molecular level. 21,43–45 The utilization of heterogenized CoPc with carbon nanotubes (CNTs) as a support is prevalent for efficient CO 2 -to-CO reduction, owing to its high activity (overpotential of ca. 0.5 V, current density = 15–20 mA cm −2 ) and selectivity (>90%).…”
