Superior Performance and Catalytic Mechanism of an Icosahedral Quasicrystal Al-Cu-Fe in CO₂ Reduction to CO.

ABSTRACT: Dissimilar to long-range periodic crystals, quasicrystals feature long-range aperiodic order and noncrystallographic rotational symmetry. These structural peculiarities and complexities endow it with unique properties and untold research values, together with significant challenges in decoding the structure-property relationship. Herein, the application of icosahedral quasicrystal (iQC) Al₆₃Cu₂₅Fe₁₂ as a high-performance catalyst is investigated for reducing CO₂ to CO, known as the reverse water-gas shift reaction, which is a key reaction for producing useful chemicals. Compared with the samples with similar compositions but different structures, it shows superior CO₂ conversion rate and CO selectivity. Combined with density functional
