摘要
以锰(Ⅱ)化合物和高锰酸钾为反应物,采用低热固相化学反应法,制备纳米MnO2,并对产物进行了XRD、TEM分析。结果表明:MnCl2·4H2O与KMnO4反应制得的产物为球形α-MnO2,粒径小于10nm;Mn(Ac)2·4H2O与KMnO4反应制得的产物为针状α-MnO2,直径为20nm,长为200nm。
α-MnO_2 was synthesized by solid state reaction of MnCl_2·4H_2O with KMnO_4 at lower heating. XRD、TEM techniques were used to characterize the α-MnO_2. It has been found that the kind of Mn(Ⅱ) compounds can influence the morphology and size of α-MnO_2.
