Resorcinol 1,4-phthalaldehyde resin (RPR) was successfully synthesized using a solvent-free self-assembly method employing a template (F127) and a mixture of resorcinol and 14-phthalaldehyde. After the removal of the template (F127) by heating, the PRR exhibited an ordered mesoporous structure with a size of approximately 5.8 nm. After impregnating with Pd species, a RPR supported Pd catalyst (Pd/RPR) was finally obtained, which demonstrated outstanding catalytic performance and good stability in the hydrodeoxygenation of vanillin. With an optimal catalyst, 100% conversion of vanillin and 96.7% selectivity for 2-methoxy-4-methylphenol were achieved under the reaction conditions of 2 MPa H in ethanol at 90 ℃ over 4 hours. The superior catalytic properties of Pd/RPR with high activity and stability are anticipated to be significant for future biofuel upgrades.

介孔有机树脂负载钯纳米颗粒用于香兰素的高效加氢脱氧


采用模板剂（F127）以及间苯二酚和14-苯二醛的混合物，采用无溶剂自组装方法成功合成了间苯二酚1,4-苯二醛树脂（RPR）。通过加热去除模板（F127）后，PRR呈现出尺寸约为5.8nm的有序介孔结构。经过Pd物种浸渍后，最终获得了RPR负载的Pd催化剂（Pd/RPR），该催化剂在香草醛加氢脱氧中表现出优异的催化性能和良好的稳定性。采用优化的催化剂，在乙醇中90℃、2MPa H的反应条件下，香草醛转化率100%，2-甲氧基-4-甲基苯酚选择性96.7%。 Pd/RPR 的优异催化性能以及高活性和稳定性预计对于未来生物燃料的升级具有重要意义。
