Surface Charge Transfer Enhanced Cobalt‐Phthalocyanine Crystals for Efficient CO ₂ ‐to‐CO Electroreduction with Large Current Density Exceeding 1000 mA cm ⁻² (Adv. Sci. 23/2025)

Electrochemical CO2 Reduction Carbon dioxide (CO2) can be upcycled into valuable chemicals through electrochemical reduction. In article number 2501459, Tengyi Liu, Hao Li, Hiroshi Yabu, and co-workers demonstrate that crystallization of metal phthalocyanines (M-Pc) significantly enhances their intrinsic catalytic activity and induces surface charge transfer, leading to high performance in electrochemical CO2 reduction. The resulting cobalt phthalocyanine (CoPc) electrode exhibits a world-record CO current density and outstanding long-term stability, outperforming all previously reported Pc-based catalysts.
