The bio-based platform molecule furfural was converted to the high value chemical cyclopentanone over Ru/C (0.5 wt%) and AlPO catalysts in good yield (84%) with water as the medium. After screening the reaction conditions, the selectivity for cyclopentanone and cyclopentanol could be controlled by adjusting the hydrogen pressure at the temperature of 433 K. Herein, we propose a new mechanism for the synergistic catalysis of a Bronsted acid and Lewis acid for the conversion of furfural to cyclopentanone through the cyclopentenone route, which is catalyzed by Ru/C and AlPO. In addition, based on cyclopentanone, higher octane number cyclic alkanes (>85% selectivity), which are used as hydrocarbon fuels, were synthesized a C-C coupling reaction followed by hydrodeoxygenation.
在以水为介质的条件下，生物基平台分子糠醛在Ru/C（0.5 wt%）和AlPO催化剂上被转化为高价值化学品环戊酮，产率良好（84%）。在筛选反应条件后，在433 K的温度下，通过调节氢气压力可以控制环戊酮和环戊醇的选择性。在此，我们提出了一种新的协同催化机理，即由Ru/C和AlPO催化，通过环戊烯酮途径将糠醛转化为环戊酮的布朗斯特酸和路易斯酸协同催化机理。此外，基于环戊酮，通过碳-碳偶联反应随后进行加氢脱氧合成了用作烃类燃料的更高辛烷值的环烷烃（选择性>85%）。
