CO2/CO co-feeds and tandem catalysts for C–C coupling

The electrocatalytic CO₂ recycling into excessive added-value merchandise has been attracting large consideration for years. Co-feeding CO₂/CO and utilizing tandem catalysts now are well-recognized methods to facilitate C–C coupling and the manufacturing of C²⁺ merchandise. In a pioneering paper printed in 2019 in Nature Nanotechnology, Wang et al. introduced preliminary evidences concerning the dominant contribution of the *CO (from CO)–*CO (from CO₂) cross-coupling pathway over a large electrode potential vary and designed tandem catalysts that realized enhanced ethylene manufacturing charge (Nat. Nanotechnol. 14, 1063–1070; 2019).
