对称性凹多面体六方相 CuS 微晶的溶剂热法制备研究

摘要

用CuSO4为铜源，硫粉为硫源，无水乙醇为溶剂，在180℃，反应12 h，用溶剂热法制备了由纳米片自组装对称的凹多面体CuS微晶。用X射线粉末衍射仪（XRD）、场发射扫描电子显微镜（FESEM）、透射电镜（TEM）及选区电子衍射（ SAED）等对产物的成分、形状和尺寸进行了表征分析。结果表明，CuS微晶具有对称性凹多面体结构，该方法操作简单，反应条件温和并且有较高的重复性和可控性，是合成材料的一种有效方法。%Pure hexagonal copper sulfide micro-crystals with symmetric concaved polyhedrons were syn-thesized by ethanol solvothermal method and using CuSO 4 and S as raw materials , ethanol as solvent .The reaction was processed at 180 ℃for 12 h.The composition, shape and size of synthetic copper sulfide micro-crystals are characterized by the equipments of XRD , FESEM, TEM and SAED.The result reveals that the copper sulfide crystals are symmetric concaved polyhedrons .It is a simple, gentle and effective synthesis method for micro-crystals materials.
