摘　　要：传统MoS2加氢催化剂粒径大、油溶性差而催化效率相对较低。纳米粒子合成方法很多,其中液相化学合成技术尤其水(溶剂)热、微乳液、单层二硫化钼重堆积和微波液相介电加热法等更为便捷、高效。在油溶性纳米MoS2的合成中,表面修饰剂的选择最为关键。综述了油溶性纳米MoS2的合成、表征和应用研究进展,提出了高稳定性、高活性和油溶性纳米MoS2加氢催化剂高效合成优化参数,为实现工业应用提供了参考。Conventional molybdenum disulfide hydrogenation catalysts are inferior in catalytic efficiency due to their relatively larger particle size and lower oil-solubility. Among the synthesis methods for nanoparticles, liquid phase chemical preparation techniques, especially hydrothermal, solvent thermal, microemulsion, restacking of monolayers of molybdenum disulfide and microwave dielectric heating method, are more facile and efficient. Selection of appropriate Surface-modifying material is a key factor to synthesis of oil-soluble molybdenum disulfide nanoparticles. Advances in synthesis, characterization and application of oil-soluble nanoparticle molybdenum disulfide hydrogenation catalysts were reviewed. Optimal parameters for synthesis of oil-soluble nanoparticle molybdenum disulfide hydrogenation catalysts with high catalytic activity, high stability and high oil-solubility were proposed.
