生物质加氢生产高附加值化学品是一种有效的利用途径。然而，负载式单金属催化体系仍然表现出较低的性能。在本研究中，不同的非贵金属纳米颗粒（NPs）被负载在具有高比表面积的氮掺杂多孔碳（M/HNPC）上，并用于糠醛（FF）的加氢反应。实验结果表明，Ni/HNPC的性能优于Fe、Co和Cu。DFT结果表明，Ni/HNPC的催化活性与Ni金属本身的内在催化性能密切相关。Ni/HNPC在110℃、4 h的温和条件下，FF转化率为95.2%，糠醇（FOL）选择性为94.8%，这主要是由于金属Ni与HNPC载体之间的协同作用。此外，由于Ni/HNPC载体的高比表面积和N掺杂也提高了Ni/HNPC催化剂的稳定性。本研究为单金属催化转化生物质提供了重要的参考依据。
The hydrogenation of biomass into high added‐value chemicals is an efficient way of utilization. However, supported monometallic catalytic systems still show low performance. In this study, different non‐noble metal nanoparticles (NPs) are supported on hierarchically nitrogen‐doped porous carbon (M/HNPC) with high specific surface area and used in the hydrogenation reaction of furfural (FF). The experiment results exhibited that the performance of Ni/HNPC is more superior than Fe, Co and Cu. The DFT results showed that the catalytic activity of Ni/HNPC was strongly related to the intrinsic catalytic performance of Ni metal itself. The Ni/HNPC obtains the 95.2% FF conversion and 94.8% furfuryl alcohol (FOL) selectivity under mild conditions at 110 °C and 4 h, which is mainly due to the synergistic effect between metallic Ni and HNPC support. In addition, the stability of the Ni/HNPC catalyst also has been improved because of the high specific surface area and N‐doped of HNPC support. This work provides an important reference for biomass conversion with a monometallic catalyst by controlling the metal types and supports.
