摘要：

Cobalt phthalocyanine (CoPc)-modified two-dimensional alpha-cobalt hydroxide (alpha-Co(OH)(2)) catalysts exhibited excellent electrochemical performance for the reduction of CO2 to CO. The faradaic efficiency (FE) and current density reached 98.4% and 22.4 mA cm(-2), respectively. Due to the strong interaction between the metal active sites and the support, the 4.1%-CoPc/alpha-Co(OH)(2) complex displayed a favorable electron density configuration, efficient charge transfer and a large electrochemical surface area.
