  studies reveal that the reaction proceeds through two possible reaction pathways, including the direct cleavage of ether bonds and the formation of intermediates with one hydrogenated benzene ring, for all examined types of ether bonds, namely, 4‐O‐5, α‐O‐4, and β‐O‐4.

  裂解醚键是木质素增价的关键但具有挑战性的步骤。为了有效地实现这种转化，需要开发耐用的催化剂或催化体系。在这项研究中，蒙脱石（MMT）负载的Ru（表示为Ru / MMT）被制成双功能多相催化剂，通过转移氢解作用裂解各种类型的醚键，而无需使用任何其他酸或碱。发现制备的Ru / MMT材料可有效催化各种木质素模型和木质素衍生酚的裂解。主要产品是环己烷（燃料）和环己醇（关键中间体）。富电子的Ru与MMT上酸性位点之间的协同作用有助于Ru / MMT的优异性能。

  (Alkyl-)cyclohexane diols are of high value as industrial reagents and resources, but current producing methods are still unsustainable. Herein, a new method of producing (alkyl-)cyclohexane diols using lignin derived phenols with yield as high as 91.2 % by selective hydrogenolysis is firstly achieved over NbO and Ni/MCM-41. The hydrogenolysis is completed by designing two-step reactions compositing

  (烷基)环己二醇作为工业试剂和资源具有很高的价值，但目前的生产方法仍然不可持续。在此，首次在NbO和Ni/MCM-41上实现了一种利用木质素衍生酚通过选择性氢解生产(烷基-)环己烷二醇的新方法，收率高达91.2%。通过设计木质素酚类C(sp)-O键的选择性裂解和苯环的选择性加氢复合的两步反应来完成氢解，实现了高选择性。与商用固体酸相比，NbO 在 C(sp)-O 键断裂方面表现出优异的活性和长寿命。通过详细的表征对强大的催化性能进行了彻底分析，并将其归因于产生的丰富的氧空位，这导致更强的L酸并吸附木质素衍生酚中的甲氧基，同时与酸位点相互作用以促进L酸的裂解。 C(sp)-O键。 Ni/MCM-41很容易完成苯环的选择性加氢。在与普遍合成的（烷基-）环己烷二醇的反应中探索了更多木质素衍生的酚。该工作为木质素酚类合成高附加值化学品提供了新的应用，为生物炼制的可持续发展做出了贡献。
