摘要

本文制备了一系列双金属Ni-Cu/ZSM-5催化剂，对木质素模型化合物的氢解进行了表征和研究。本研究旨在了解通过简单的水热/还原合成制备的负载双金属纳米颗粒的性质，这些纳米颗粒在生物精炼设施中的潜在应用。研究发现，金属负载和相对金属含量的变化对纳米颗粒内金属的分离有重要影响，而这反过来又影响了所研究反应的材料的反应活性。研究结果还强调了木质素提取方法对未来生物精炼的重要性。

Lignin Model Compound Hydrogenolysis Over ZSM-5-Supported Cu/Ni Bimetallic Transition Metal Catalysts

In this paper, a series of bimetallic Ni-Cu/ZSM-5 catalysts was prepared, characterized, and investigated in the hydrogenolysis of lignin model compounds. This study is aimed at the understanding of the properties of supported bimetallic nanoparticles prepared via a facile hydrothermal/reduction synthesis for potential applications within biorefining facilities. Changes in metal loadings and relative metal contents were found to have important effects on the separation of the metals within the nanoparticles, and this in turn affected the reactivity of the materials for the investigated reaction. The results also highlight the importance of lignin extraction methods for the future of biorefining.
