中文摘要：

在低温水热条件下，以不同硫源和银片为反应物，制备出了微纳米级Ag2S晶体，其中以硫粉为硫源、乙醇为溶剂时制备出了少见的拥有中空管状形貌的Ag2S微纳米材料，并用X射线粉末衍射仪（XRD）、扫描电子显微镜（SEM）分别对产物Ag2S晶体的结构和形貌进行了表征和分析。

英文摘要：

Micro/nano Ag2S was synthesized via a convenient hydrothermal route at relatively low temperature, with sulfur - containing materials and silver foil as reactants. Interestingly, micro/nano Ag2 S tubes cound be obtained when the Ag foil reacted with S powder in a ethanol system/solvent. Several techniques including X - ray diffraction （XRD） and scanning electron microscopy （SEM） were used to characterize the products. The final products were tes- tified micrometer - tube Ag2S crystalline. Keywords micro/nano materials hydrothermal synthesis Ag2S crystal
