Efficient catalytic transfer hydrogenation of biomass-based furfural to furfuryl alcohol with recycable Hf-phenylphosphonate nanohybrids<\/strong><\/p>\n

Recently, Dr. Hu Li supervised by Profs. Zhen FANG and RL Smith has synthesized an acid-base bifunctional nanohybrid phenylphosphonic acid (PhP) \u2013 hafnium (1:1.5) through assembly of PhP with HfCl4 for catalytic transfer hydrogenation of furfural (FUR) to furfuryl alcohol (FFA) using 2-propanol as both reaction solvent and hydrogen donor source. An FFA yield of 97.6% with formation rate of 9760 \u03bcmol g-1 h-1 at 99.2% FUR conversion was obtained with the reaction system at 120\u202f\u00b0C for 2\u202fh reaction time. Activation energy (Ea) was estimated to be 60.8\u202fkJ\/mol with respect to FUR concentration, which is comparable with or even lower than Ea values attained over metal catalysts. The pronounced catalytic activity of PhP-Hf (1:1.5) is attributed to its moderate acidity and relatively strong basicity. The PhP-Hf (1:1.5) catalyst was demonstrated to maintain its activity for five consecutive reuse cycles.<\/p>\n
