Facet engineering of MOF supports regulates product selectivity in CO<sub>2</sub> photoreduction by modulating electron and proton supply to COF shells.
Ontology highlight
ABSTRACT: Selective photoreduction of CO2 with H2O to hydrocarbons is challenged by inadequate and uncontrollable electron and proton feeding. Herein, this limitation is overcome by integrating H2O dissociation, CO2 reduction, and O2 evolution catalysts into a dual S-scheme heterojunction and regulating exposed facets of the heterojunction supports. In this design, H+ and OH- species generated by H2O dissociation on the NH2-MIL-125 support transfer to the T-COF shell and Fe2O3 insert for CO2 reduction and O2 evolution, respectively. Mechanistic investigations reveal that increasing NH2-MIL-125{001} facet exposure promotes proton spillover, while si
