摘　　要：研究以四水合乙酸锰为锰源,单质硫粉为硫源,分别以乙醇、乙二醇及丙三醇为溶剂,在不添加任何表面修饰剂的条件下采用溶剂热反应制备出Mn S材料。用X射线粉末衍射仪(XRD)和扫描电镜(SEM)对产物进行了物相和形貌表征。结果表明,通过控制溶剂类型、反应物的投料比、溶剂热温度及反应时间,可以控制合成α-Mn S和γ-Mn S。丙三醇为溶剂时所得的α-Mn S材料粒度更细,光催化效果最好。MnS was successfully synthesized using manganous acetate tetrahydrate and sulfur powder as raw materials and ethanol, ethylene glycol, glycerol as solvent without any surface modification agent via solvothermal synthesis. Samples were characterized by X-ray powder diffraction （XRD） and scanning electron microscope （SEM）. The α-MnS and γ-MnS nanocrystalline with different structures were synthesized via varying the experimental parameters including the mole feed ratio of manganese and sulfur precursors, reaction temperatures and reaction durations, α-MnS prepared using glycerol as solvent exhibited the best photocatalytic activity.
