【摘要】 采用水热法,以KMnO₄和无机酸为原料,在Mn片上制备出了MnO₂薄膜。利用X射线衍射（XRD）和场发射扫描电子显微镜（FE-SEM）对产物的晶型和显微结构进行了表征。结果表明,不同阴离子环境中合成的产物均为δ-MnO₂,但Cl^-对结晶和生长过程最有利;而在增加薄膜致密度和增强薄膜与基片结合力上,阴离子作用顺序分别为:PO_4³->Cl>SO_4²-和Cl>SO_4²->PO_4³-。更多还原

【Abstract】 MnO₂ film was synthesized on Mn substrate by hydrothermal method,using KMnO₄ and inorganic acid as main raw materials.The as-prepared samples were characterized by X-ray diffraction（XRD）and field emission scanning electron microscope（FE-SEM）.The results showed that samples prepared with different anions were all belongs toδ-MnO₂,and Cl^- is most beneficial for crystallization and growth.Furthermore,on increasing the film density,different anion effect is in order as PO₄^3-> Cl^-> SO₄^2-as to increasing adhesion between film and substrate,the order is Cl^-> SO₄^2-> PO₄^3-.更多还原
