Enhanced Cuprophilic Interactions in Crystalline Catalysts Facilitate the Highly Selective Electroreduction of CO2 to CH4

Lei Zhang et al.

Summary: Cu(I)-based catalysts are essential for the electrocatalytic CO2 reduction, and in this study, two stable copper(I)-based catalysts with inherent cuprophilic interactions were synthesized for highly selective CO2-to-CH4 conversion.

Highly Selective Tandem Electroreduction of CO2 to Ethylene over Atomically Isolated Nickel-Nitrogen Site/Copper Nanoparticle Catalysts

Dong-Li Meng et al.

Summary: An effective tandem catalysis strategy was developed to improve the selectivity of CO2RR towards C2H4, using multiple distinct catalytic sites in local vicinity.
