- Аннотация: Platinum and palladium catalysts supported on two types of porous aromatic frameworks, PAF-30 and PAF-30-NH2 (modified with amino groups), were examined in furfural hydrogenation. The influence of temperature, reaction time and solvent on selectivity and activity of the catalysts was investigated. Using isopropanol as solvent and conducting experiments at 40 ℃ led to sufficient decrease of side products yields. According to TEM Pt-PAF-30 and Pd-PAF-30-NH2 catalysts are characterized with uniform particles distribution on support. Elemental analysis shows a difference in palladium content between Pd-PAF-30 and Pd-PAF-30-NH2: 4.6% and 6.8% respectively. Whereas platinum catalysts have both 5.4% of metal. Catalyst Pt-PAF-30 was highly selective to tetrahydrofurfuryl alcohol (83% yield), whereas the catalyst Pd-PAF-30-NH2 exhibited unusually high selectivity towards tetrahydrofurfural (77% yield). All studied catalysts were also tested in the hydrogenation of 5-hydroxymethylfurfural and 5-methylfurfural, in these experiments up to 20% yield of 1-hydroxy-4-hexen-2-one was observed.
