| 摘 要： | 分别采用硫脲、L-胱氨酸和硫磺为硫源水热合成了三种MoS2催化剂，对其结构和形貌特征进行了表征，并以对甲酚为探针化合物，比较研究了三种MoS2的加氢脱氧（HDO）催化活性。结果表明，硫源对MoS2晶体结构的影响不大，但对其形貌和比表面积影响较大。与商业MoS2相比，所制备的MoS2催化剂都表现出更高的HDO活性；其中，以硫脲为原料合成的MoS2具有较高的比表面积和花状结构，其催化活性最高，在300℃下进行对甲酚的HDO反应，脱氧度可达99.3%。

| Abstract: | Three MoS2 catalysts were synthesized by a hydrothermal method using different sulfur precursors such as thiourea, L-cystine and sulfur powder; their differences in the structure, morphology, and catalytic activity in the hydrodeoxygenation (HDO) of p-cresol were comparatively investigated. The results illustrated that the sulfur source has a significant influence on the morphology and surface area of the as-synthesized MoS2 catalysts. All the hydrothermally synthesized MoS2 catalysts show much higher activity in HDO than the commercial MoS2 sample. Among three MoS2 catalysts, the one prepared from thiourea, with a high surface area and flower-like morphology, exhibits the highest activity in HDO; over it, a deoxygenation degree of 99.3% is achieved at 300°C. |
