摘要

作为木质纤维素生物质中含量第二丰富的成分和可再生芳香族化合物的最大来源,木质素在替代有限的、不可再生的化石油方面显示出巨大的潜力,成为生产燃料和芳香族化学品的可再生原料。因此,开发有效的方法将木质素转化为生物燃料和有价值的化学品是非常重要的。电化学方法被认为是可扩展的,不含氧化剂/还原剂,易于控制,并且可以在温和的条件下进行。本文首先综述了木质素的结构和解构方法。然后详细讨论了木质素的电化学转化途径,包括介导电氧化、电酶氧化、光电氧化和直接电氧化。并简要介绍了木质素衍生单体化合物的应用。最后,总结了不同木质素电化学升级方法的优点和面临的挑战;同时,对木质素生物质增值的未来研究提出了建议。

Electrochemical valorization of lignin: Status, challenges, and prospects

As the second most abundant component of lignocellulosic biomass and the largest source of renewable aromatic compounds, lignin shows great potential to replace finite, non-renewable fossil oils and becomes a renewable feedstock for the production of fuel and aromatic chemicals. Therefore, it is highly important to develop efficient methods to convert lignin into biofuels and valuable chemicals. Electrochemical approaches are considered to be scalable, oxidant/reductant free, easy to control, and can be conducted under mild conditions. This review firstly overviews the structure and deconstruction methods of lignin. And then, different electrochemical lignin conversion approaches, including mediated electrooxidation, electroenzymatic oxidation, photoelectrochemical oxidation, and direct electrooxidation, are discussed in detail. The application of lignin-derived monomeric compounds is also briefly introduced. Finally, the advantages and challenges of different electrochemical lignin upgrading approaches are summarized; meanwhile, suggestions are made for future research on lignin biomass valorization.
