Highly efficient CO₂ hydrogenation to long-chain linear α-olefins <i>via</i> CO intermediate enrichment over Na/FeMn/ZrO₂ catalysts.

ABSTRACT: Although significant progress has been made in the oriented conversion of CO₂ to long-chain linear α-olefins (LAOs), cooperatively regulating C-O bond activation and C-C coupling via tailored catalyst microstructures remains a persistent challenge. Herein, a highly efficient Na/FeMn/ZrO₂ catalyst has been fabricated through a covalent anchoring strategy, which achieves a LAOs/C₄₊ selectivity of 68% and an O/P ratio of 5.1 in CO₂ hydrogenation to LAOs. There is a pronounced interaction between Fe species and MnCO₃ in Na/FeMn/ZrO₂ catalysts, which promotes the formation and stabilization of iron carbides. Meanwhile, Fe₅C₂-ZrO₂ interfaces possess strong adsorption capacity for CO intermed
