Selective Hydrogenolysis of Biomass‐Derived Aromatic Alcohols over 2D‐Mo2COx MXene by a Reversible Redox‐Relay Mechanism

is activated to remove residual oxygen species, boosting selective hydrogenolysis while suppressing furan and CH=O hydrogenation. Furthermore, the catalyst exhibited broad universality for synthesizing methyl aromatics from various furfuryl alcohols, benzyl alcohols, and hydroxycyclopentenones. This study presents a novel redox-relay mechanism in advanced MXene catalysis, offering a straightforward hydrogenolysis pathway for challenging substrates.
