Oxygen-modulated engineering of Cu0-Cu+ interfaces for CO2-to-C2H4 photoreduction.
Ontology highlight
ABSTRACT: CO2-to-hydrocarbon fuel conversion via artificial photosynthesis is limited by catalyst poisoning under high O2 partial pressures and sluggish C2-product formation. Herein, Ru0.6Cu1(Cu0-Cu1+)/CeO2 catalysts with adaptive O2 tolerance are prepared by O2-mediated dynamic interfacial reconstruction. Single-atom Ru doping at Ce lattice sites creates a trigonal prismatic coordination configuration, enabling proton-coupled electron transfer and accelerating H2O dissociation. Photothermal effect promotes O2-driven self-assembly of Cu0-Cu1+ charge-gradient interfaces within Ru/Cu alloy clusters, thereby optimizing the adsorption behavior of
