Cu, Co and Zn modified N-doped porous carbons (CuCo/Zn@NPC) are prepared using a polymetallic homogeneous doping and self-templating method as high performance non-noble metal catalysts for the hydrogenation of furfural (FF) to furfuryl alcohol (FAL). The CuCo/Zn@NPC-600 catalyst after treatment at 600 °C shows a superior catalytic activity with nearly 100% conversion of FF and an almost 100% selectivity of FAL using H₂ at 140 °C. Meanwhile in the catalytic transfer hydrogenation (CTH) using 2-propanol as a H-donor, the conversion of FF reaches 95.8% and the selectivity of FAL is 99.1%. The results show that the Zn dopant leads to 37.3 times higher yield on the CuCo/Zn@NPC-600 catalyst than that on CuCo@NPC-600, and 2.3 times higher than that on Co/Zn@NPC-600 with Cu dopants. The efficient activity of the CuCo/Zn@NPC-600 catalyst is mainly due to the highly dispersed metal nanoparticles, the advanced porous structure resulting from Zn escape from the precursor template, and the synergistic effect between Cu and Co. Furthermore, the CuCo/Zn@NPC-600 catalyst exhibits good recyclability in FF hydrogenation in four cycle tests. The advanced synthesis method using a homogeneous doping and self-templating strategy sheds light on preparing effective catalysts for hydrogenation of biomass-based compounds.

调整多金属掺杂ZIF衍生材料的合成，以将糠醛有效氢化为糠醇。

铜，钴和锌改性的N掺杂多孔碳（CuCo / Zn @ NPC）是使用多金属均相掺杂和自模板化方法制备的，用于将糠醛（FF）加氢成糠醇的高性能非贵金属催化剂（ FAL）。经过600°C处理的CuCo / Zn @ NPC-600催化剂显示出优异的催化活性，FF的转化率接近100％，使用H ₂时FAL的选择性接近100％在140°C下。同时，在以2-丙醇为氢供体的催化转移加氢（CTH）中，FF的转化率达到95.8％，FAL的选择性为99.1％。结果表明，Zn掺杂剂在CuCo / Zn @ NPC-600催化剂上的产率比CuCo @ NPC-600的产率高37.3倍，比Co / Zn @ NPC-600的Cu掺杂剂的产率高2.3倍。CuCo / Zn @ NPC-600催化剂的有效活性主要归因于高度分散的金属纳米颗粒，Zn从前体模板逸出而形成的先进多孔结构以及Cu与Co之间的协同作用。此外，CuCo / Zn @ NPC-600催化剂在FF加氢中表现出良好的可循环性，经过四个循环测试。
