Bimetallic phthalocyanine heterostructure used for highly selective electrocatalytic CO2 reduction

Heterogeneous molecular catalysts, such as metal phthalocyanines, are efficient electrocatalysts for CO2 reduction reaction (CO2RR). However, the rational design and synthesis of a molecular catalyst-based heterostructure for CO2RR remains challenging. Herein, we developed a crystalline bimetallic phthalocyanine heterostructure electrocatalyst (CoPc/FePc HS), which achieved an excellent CO2-to-CO conversion efficiency (99%) and outstanding...
