摘　　要：木质素主要由羟基或甲氧基取代的苯丙烷基结构组成,是自然界中唯一可大量生产芳香族化学品的可再生原料。通过选择合适的催化剂,打断其长链结构,高选择性地获得某种或某类目标产物是木质素综合利用的重要途径。金属硫化物催化剂由于具有良好的加氢及脱氧活性,几十年来被广泛应用于木质素催化转化领域。本文对金属硫化物催化剂在木质素及其模型化合物催化转化中的应用进行了综述,从活性组分、载体材料、反应条件及反应机理等方面进行了总结和分析。在此基础上,指出了金属硫化物催化剂在木质素催化降解中面临的难题,并对未来研究提出了建议与展望。Lignin is mainly composed of hydroxy-substituted or methoxylated phenyl propane structures and serves as the only renewable bulk feedstock in nature for producing aromatic chemicals. By using suitable catalysts,the long chain structures of lignin can be selectively broken down to obtain different target products.This has been regarded as an important approach for the comprehensive utilization of lignin. Due to the high activity of hydrodeoxygenation,transition metal sulfide catalysts have been used in lignin conversion in recent decades. In this review,the application of transition metal sulfide catalysts in the catalytic conversions of lignin and its model compounds are summarized. The active components,support materials,reaction conditions and reaction mechanism are presented in detail. The existing challenges of sulfide catalysts in the degradation of lignin are discussed. Finally,potential solutions and future trends of this field are presented.
