Abstract
The aim of the current work was to study the activity of supported palladium catalysts based on porous aromatic frameworks (PAF) in vanillin hydrogenation, and to develop the methods for controlling their activity and selectivity by modifying the PAF structure with various functional groups. Using unmodified PAF-30, its sulfonated derivative PAF-30-SO3H, and that of PAF-30-TEA modified with CH2N+(C2H5)3 groups, palladium catalysts were synthesized and tested for HDO of lignin components. This investigation provides one potential route for the development of efficient catalysts for hydrodeoxygenation by the adjustment of the composition of the catalyst and its appropriate derived properties.
