电化学法制备氯氧化锑Sb_4O_5 Cl_2

Electrochemical Synthesis of Antimony Oxychloride Sb_4O_5Cl_2

以金属锑为阳极,钛、不锈钢等导电材料为阴极,HCl溶液或含NaCl的HCl溶液为电解液,在单室电解槽中采用电化学牺牲阳极法溶解金属锑．制备了粒径为10 nm的超细金属锑．该金属锑与盐酸溶液反应生成了氯化锑溶液,再经水解得到了氯氧化锑Sb_4O_5Cl_2。产品通过X射线粉末衍射(XRD)、扫描电子显微镜(SEM)和透射电镜(TEM)测试技术进行了表征。

The antimony oxychloride was synthesized by means of electrochemical method. The anode comprised of sacrificial metal Sb; the cathode was an indifferent conducting material; the electrolyte could be a chloride salt soluble in the hydrochloric acid . Uhrafine metal Sb （ 10nm ） was directly prepared by electrosynthesis, and antimony oxychloride was synthesized through hydrolyzing antimony chloride solution which was formed by the reaction of uhrafine Sb and hydrochloric acid. The synthetic condition was discussed and the structure and morphology of the product were characterized by virtue of titration, XRD, SEM and TEM. The synthetic process is simple without contamination.
