Cu 2 O@ZIF-8 hybrid catalysts with optimized electronic structures tailored by interfacial interactions for efficient electrocatalytic CO 2 reduction

Cu 2 O@ZIF-8 efficiently converts CO 2 to CO and CH 4 with high faradaic efficiencies (84.7% CO, 78.8% CH 4 ) and stability (20 h). Enhanced by Cu–N/Zn–N sites and sp 2 carbon, it outperforms pure ZIF-8, offering a promising MOF-based CO 2 RR catalyst.
