Conversion of biomass-derived furfural platform compound to value-added tetrahydrofurfuryl alcohol (THFL) molecule is a sustainable route, and an efficient nonnoble metallic catalyst is a key factor for this reaction. In this work, Ni@C@CNT composite as a highly effective catalyst for hydrogenation of furfural to tetrahydrofurfuryl alcohol was synthesized by one-step pyrolysis of Ni-centered metal organic framework (Ni-MOF) doping with carbon nanotube (CNT). For comparison, Ni@C catalyst derived directly from Ni-MOF was also synthesized. The characterization results show that the doping of CNT promotes high dispersion of active sites and formation of Ni₃C phase which has Pt-like catalytic activity. Therefore, the obtained Ni@C@CNT exhibited excellent activity in furfural hydrogenation (99.1% furfural conversion and 94.7% THFL yield at 120°C, 4 h, 4-MPa initial hydrogen pressure). Ni@C@CNT also shows good stability in reuse test. Current work presents a facile method for preparation of nonnoble metallic catalysts with high efficiency.

由 CNT 掺杂的 Ni-MOF 衍生的 Ni@C@CNT 催化剂用于糠醛加氢制四氢糠醇

将生物质衍生的糠醛平台化合物转化为增值的四氢糠醇（THFL）分子是一条可持续的路线，高效的非贵金属催化剂是该反应的关键因素。在这项工作中，Ni@C@CNT复合材料作为糠醛加氢制四氢糠醇的高效催化剂，通过一步热解掺杂碳纳米管（CNT）的Ni中心金属有机骨架（Ni-MOF）合成。为了比较，还合成了直接衍生自 Ni-MOF 的 Ni@C 催化剂。表征结果表明，CNT的掺杂促进了活性位点的高度分散和Ni _{3的形成。}C相具有类Pt的催化活性。因此，所获得的 Ni@C@CNT 在糠醛加氢中表现出优异的活性（在 120°C、4 h、4-MPa 初始氢气压力下，糠醛转化率为 99.1%，THFL 产率为 94.7%）。Ni@C@CNT 在重复使用测试中也表现出良好的稳定性。目前的工作提出了一种高效制备非贵金属催化剂的简便方法。
