Alloyed molybdenum enables efficient alcohol hydrodeoxygenation with supported bimetallic catalysts.

ABSTRACT: Bimetallic heterogeneous catalysts combining group 9 metals (Rh, Ir) or group 10 metals (Ni, Pd, Pt) with Mo on a silica-based support have been synthesized via surface organometallic chemistry and assessed in their catalytic activity for the hydrodeoxygenation (HDO) of alcohols with particular emphasis on the structural evolution of the catalysts and the role of Mo. The investigation was conducted with an air-free approach to isolate any sample alterations exclusively to those caused by the reaction. Structural analysis was performed using a combination of (S)TEM, IR, and XAS. It was found that Ir-Mo/SiO₂, Rh-Mo/SiO₂, and Pt-Mo/SiO₂ display high activity for primary, secondary, and tertiary alcohol deoxygenation, while Pd-Mo/SiO₂ selectiv
