摘要:木质素在化学工艺、生物制药、纳米生物技术等多个领域均具有广泛的应用，但木质素拥有的复杂高分子结构使其利用工艺还不成熟，目前多数被用作低价值燃料，高效利用木质素的方法成为研究讨论的热点。还原解聚是利用高分子物质最常使用的方法之一，本文从木质素的氢气还原解聚、供氢试剂还原解聚、其他还原解聚方法等方面对木质素的解聚方法以及解聚产物进行了综述，并对木质素还原解聚的发展前景进行了展望。

Abstract:Lignin has a wide range of applications in many fields such as chemical processes， biopharmaceuticals， and nano-biotechnology， etc. However， due to the complex polymer structure of lignin， the utilization process of ligin is immature and currently used as low-value fuel. The way to efficiently use lignin has become a hot topic of research and discussion. The reduction and depolymerization was one of the most commonly used methods for the utilization of polymers. In this paper， the depolymerization methods and products of lignin were reviewed from various aspects， such as hydrogen reduction and depolymerization of lignin， reduction and depolymerisation of hydrogen-supplying reagents， and other reduction and depolymerization methods. And the prospects for the development of reduction and depolymerization of lignin were envisioned.
