Photothermal CO₂ conversion to ethanol through photothermal heterojunction-nanosheet arrays.

ABSTRACT: Photothermal CO₂ conversion to ethanol offers a sustainable solution for achieving net-zero carbon management. However, serious carrier recombination and high C-C coupling energy barrier cause poor performance in ethanol generation. Here, we report a Cu/Cu₂Se-Cu₂O heterojunction-nanosheet array, showcasing a good ethanol yield under visible-near-infrared light without external heating. The Z-scheme Cu₂Se-Cu₂O heterostructure provides spatially separated sites for CO₂ reduction and water oxidation with boosted carrier transport efficiency. The microreactors induced by Cu₂Se nanosheets improve the local concentration of intermediates (CH₃* and CO*), thereby promoting C-C coupling process. Photothermal eff
