Highly porous carbon was prepared via a zeolite hard templating route. Subsequent melamine treatment produced nitrogen-functionalized carbon (NPC), which was used as a support to anchor Pd nanoparticles (Pd/NPC) of sizes 2–4 nm using the chemical reduction method. Various analytical techniques were used to characterize the textural properties, structure, and chemical nature of the catalyst. Pd/NPC was then employed as a catalyst for the transfer hydrogenation of biomass-derived furfural (FF) to furfuryl alcohol (FFA) with alcohol as a hydrogen donor, and the effect of temperature, hydrogen donor species, reaction time, and catalysts loading were investigated. The Pd/NPC catalyst was reusable up to five times without any apparent loss of its activity and selectivity. A possible mechanistic pathway for the catalytic transfer hydrogenation of FF over Pd/NPC catalyst was proposed.

氮掺杂多孔碳负载钯催化生物基糠醛的催化转移加氢
通过沸石硬模板路线制备了高度多孔的碳。随后的三聚氰胺处理产生了氮官能化碳(NPC),使用化学还原方法将其用作固定大小为2-4 nm的Pd纳米颗粒(Pd / NPC)的载体。各种分析技术被用来表征催化剂的质构性质,结构和化学性质。然后将Pd / NPC用作催化剂,以乙醇为氢供体将生物质衍生的糠醛(FF)转移氢化为糠醇(FFA),以及温度,氢供体种类,反应时间和催化剂负载量的影响被调查了。Pd / NPC催化剂可重复使用多达五次,而其活性和选择性没有任何明显的损失。
