Lignin valorization has gained increasing attention over the past decade. Being the world’s largest source of renewable aromatics, its valorization could pave the way towards more profitable and more sustainable lignocellulose biorefineries. Many lignin valorization strategies focus on the disassembly of lignin into aromatic monomers, which can serve as platform molecules for the chemical industry. Within this framework, the oxidative conversion of lignin is of great interest because it enables the formation of highly functionalized, valuable compounds. This work provides a brief overview and critical discussion of lignin oxidation research. In the first part, oxidative conversion of lignin models and isolated lignin streams is reviewed. The second part highlights a number of challenges with respect to the substrate, catalyst, and operating conditions, and proposes some future directions regarding the oxidative conversion of lignin.

在过去的十年中，木质素的价格上涨越来越受到关注。作为世界上最大的可再生芳烃来源​​，其价格上涨可能会为建立更具盈利性和可持续性的木质纤维素生物炼油厂铺平道路。许多木质素的增价策略集中于将木质素分解为芳香族单体，这些芳香族单体可以用作化学工业的平台分子。在此框架内，木质素的氧化转化非常令人感兴趣，因为它能够形成高度官能化的有价值的化合物。这项工作提供了对木质素氧化研究的简要概述和批判性讨论。在第一部分中，对木质素模型和分离的木质素流的氧化转化进行了综述。第二部分重点介绍了有关底物，催化剂，
