Orbital-Level-Directed Selective CO 2 -to-C 2 H 4 Photoreduction via Se Vacancies and Plasmonic Pt

The photocatalytic reduction of CO2 to C2 products with high selectivity under visible light remains a grand challenge primarily due to the high-energy barriers and kinetic complexities of C–C coupling. The current strategies primarily concentrate on augmenting the number of carriers to activate the multielectron transfer system, often overlooking the mechanism by which the coupling effect of catalyst surface energy influences intermediates. Herein, we report a strategy that synergizes vacancies and plasmonic Pt to steer the high energy of key intermediates for selective C2 production. The constructed catalyst achieves an exceptional ethylene yield of 86.81 μmol·g–1·h–1 with near-unity selectivity (∼100%),…
