Oxygen vacancy-enhanced hydrogen spillover on a bifunctional PdFe/TiO 2− x catalyst for highly selective direct hydrodeoxygenation of carbonyl compounds

Key Points

• The study aims to enhance the hydrodeoxygenation process of carbonyl compounds using a Pd–Fe catalyst on TiO2.
• Utilized a Pd–Fe bimetallic catalyst supported on TiO2−x.
• Investigated the hydrogen spillover mechanism promoted by oxygen vacancies.
• Conducted reactions under mild conditions to assess yield and efficiency.
• Achieved a 99% yield of MMP from VAN during the direct hydrodeoxygenation process.
• Demonstrated effective avoidance of alcohol intermediates in the reaction.
• Highlighted the role of synergistic effects of the metals in improving catalyst performance.
