(abstract)

Dissimilar to long-range periodic crystals, quasicrystals feature long-range aperiodicorder and non-crystallographic rotational symmetry. These structural peculiarities andcomplexities endow it with unique properties and untold research values, together withsignificant challenges in decoding the structure-property relationship. Here weinvestigate the application of icosahedral quasicrystal (iQC) Al63Cu25Fe12 as a high-performance catalyst for reducing CO2 to CO, known as the reverse water-gas shift(RWGS) reaction, which is a key reaction for producing useful chemicals. Comparedwith the samples with similar compositions but different structures, it shows superiorCO₂ conversion rate and CO selectivity. Combined with density functional theory (DFT)calculations, the origin of the high catalytic activity of iQC Al63Cu25Fe12 has beendeciphered. It is found that for the approximant crystal of the quasicrystal, the reactiontends to occur near the icosahedral cluster. Compared to other control groups, itexhibits much lower reaction barriers during CO2 reduction to CO. This demonstratesthat the high catalytic performance of iQC Al63Cu25Fe12 stems from its internally richicosahedral cluster content. Our research exemplifies the potential of quasicrystals inthe field of catalysis and sheds light on the structure-property relationship of complexstructures.
