Research highlight: A density functional theory study on how γ-Al2O3 – Boehmite transformation affects carbon evolution during aqueous-phase reaction

This work explains the deactivation of γ-Al₂O₃ which the phase transformation of γ-Al₂O₃ to Boehmite can easily occur during liquid-phase reaction. Phase transformation of γ-Al₂O₃ can be divided into two states including
(1) partial hydroxylation of γ-Al₂O₃
(2) full hydroxylation of Boehmite. These phenomena change the behavior of these catalyst support to coking significantly. The results of this work are crucial to modified stability of the catalyst when applying γ-Al₂O₃ in the liquid phase reaction.
