来自生物质的木质素可以成为芳香族化合物的可持续来源。它的解聚可以通过氢解来完成，尽管缺乏基于廉价且丰富的金属的催化剂的开发。本文合成了一种基于氮化钛和镍的可持续复合材料，并将其用作木质素模型芳基醚氢解的催化剂。新材料在氢化反应期间的催化活性被证明上级单独的任一组分。特别地，不同的芳基醚可以在相对温和的条件下在几分钟内有效地转化为芳香族化合物和环烷烃。
Lignin from biomass can become a sustainable source of aromatic compounds. Its depolymerization can be accomplished through hydrogenolysis, although the development of catalysts based on cheap and abundant metals is lacking. Herein, a sustainable composite based on titanium nitride and nickel is synthesized and employed as catalyst for the hydrogenolysis of aryl ethers as models for lignin. The catalytic activity of the new material during hydrogenation reactions is proven to be superior to that of either component alone. In particular, different aryl ethers could be efficiently converted under relatively mild conditions into aromatic compounds and cycloalkanes within minutes.
