曼彻斯特大学研究团队开发了一种高效单原子催化剂,能在温和条件下将植物废弃物中的木质素转化为具有商业价值的化学品。1该催化剂由嵌入氮掺杂碳材料中的单个钌原子组成,研究人员通过原子级分析揭示了Ru-N4位点在激活氧气和破裂木质素中碳-氧/碳-碳键中的关键作用。1
木质素是农业和林业废弃物的主要成分,约占35%,也是自然界最大的可再生芳香化合物来源。1在优化条件下,该催化剂对木质素的转化率接近100%,能够高产率生成酚类等有价值的化学产品。1
研究团队负责人Christopher Parlett表示:"在原子水平上准确理解这些催化剂如何工作,使我们能够设计更好的材料将可再生资源转化为有价值的化学品"。1相关研究成果已发表于《ACS Catalysis》2026年第16卷第4期第3607页。1
Researchers at the University of Manchester have developed a single-atom catalyst capable of efficiently breaking down lignin from plant waste under mild conditions and converting it into valuable chemicals.1 The catalyst consists of individual ruthenium atoms embedded within a nitrogen-doped carbon material, with the Ru-N4 site playing a critical role in activating oxygen molecules and cleaving the carbon-oxygen and carbon-carbon bonds in lignin.1
The research team, including Dr. Christopher Parlett, achieved conversion rates approaching 100% under optimized conditions, generating high yields of phenolic compounds and other valuable chemical products.1 Dr. Parlett emphasized the significance of atomic-level understanding, stating: "By accurately understanding at the atomic level how these catalysts work, we are able to design better materials to transform renewable resources into valuable chemicals."1 The findings were published in ACS Catalysis in August 2026, volume 16, issue 4, page 3607.1
The breakthrough addresses a substantial opportunity in waste valorization, as lignin comprises approximately 35% of agricultural and forestry waste and represents the largest renewable source of aromatic compounds in nature.1
