摘要

以硫代硫酸钠、三氯化锑为反应原料,采用微波法合成了硫化锑微纳米材料。利用X射线衍射仪(XRD)与扫描电子显微镜(SEM)对其进行了表征。考察了表面活性剂种类、用量、反应时间、反应体系pH对硫化锑微纳米材料形貌的影响。结果表明,十六烷基三甲基溴化铵(CTAB)有利于形成硫化锑微米棒;随着CTAB浓度的增加,硫化锑微米棒的长径比逐渐减小(由9.85减小至4.77);随着反应时间的增长,长径比先增加至峰值(15min),然后逐渐减小。酸性条件有利于形成棒状结构,碱性条件易形成颗粒状结构。总之,利用微波法合成硫化锑微纳米材料极大地缩短了反应时间,并且通过控制反应条件可得到具有不同长径比的硫化锑微米棒。

Abstract

Using sodium thiosulfate and antimony trichloride as raw materials,antimony trisulfide(Sb2S3) micronanomaterials were successfully synthesized by microwave method.The prepared samples were characterized by XRD and SEM.The effects of surfactant type,dosage of surfactant,reaction time and pH value of reaction system on the morphology of Sb2S3 were investigated.The results showed that CTAB was beneficial to the formation of Sb2S3 microrods.With the increase of CTAB concentration,the length-diameter (L-D) ratio of Sb2S3 microrods decreased gradually (9.85 to 4.77).With the increase of reaction time,the L-D ratio first increased to peak value (15min) and then decreased.The rod-shaped structure was favorable to beformed under acid condition,while it was easy to form granular structure under alkaline condition.Overall,the microwave synthesis of Sb2S3 greatly reduced the reaction time,and by controlling the reaction conditions,antimony sulfide microrods with different L-D ratios can be obtained.
