The invention relates to a method for converting lignin and a model compound thereof. The method comprises the steps of dispersing the lignin model compound and the lignin into an organic solvent, then, adding a prepared oxygen-doped molybdenum disulfide catalyst (O-MoS2) into the dispersion solution, and carrying out a reaction for 2 to 24 hours under the conditions that the temperature is 160 DEG C to 260 DEG C, the pressure is 1.0MPa to 5.0MPa and hydrogen gas serves as a reducing agent, so as to efficiently convert the lignin model compound and the lignin into corresponding phenols and fine chemicals thereof with aromatic structures. 本发明涉及种木质素及其模型化合物转化的方法，将木质素模型化合物及木质素分散于有机溶剂中，然后加入制备的氧掺入二硫化钼催化剂(O-MoS)，在160～260℃，1.0～5.0MPa氢气为还原剂条件下反应2～24h高效率的转化木质素模型化合物及木质素为相应的酚类物质及其具有芳香结构的精细化学品。
