应用氧化法水热合成了Na型层状氧化锰[BirMO(Na)], 通过离子交换反应在0.1 mol/L HCl溶液中Na型层状氧化锰转化成H型层状氧化锰[BirMO(H)]. BirMO(H)在四甲基氢氧化铵[(CH3)4NOH]溶液中搅拌处理7 d后, 剥离生成了MnO2纳米层胶体分散液. 剥离的MnO2纳米层胶体分散液在pH＝4.0～11.0的精氨酸溶液中搅拌2 d, 得到了层间距为1.49 nm的精氨酸插层氧化锰纳米结构材料. 通过XRD, DSC-TGA, SEM, IR及元素分析对合成试样进行了分析表征. 结果表明精氨酸在氧化锰层间的插入量及插入形式与重组溶液的pH值密切相关, 其最大插入量为1.80 mmol/g.

Na-type layered manganese oxide [BirMO(Na)] was hydrothermally prepared by a oxidation method, then it was translated into H-type layered manganese oxide [BirMO(H)] in a 0.1 mol/L HCl solution. When BirMO(H) was treated in a (CH3)4NOH solution for 7 d, it was delaminated into MnO2 nanosheet colloid suspension. The MnO2 nanosheet colloid suspension was poured into an arginine solution of pH＝4.0～11.0 followed by stirring for 2 d, then arginine intercalated layered manganese oxide nanocomposite with a basal spacing of 1.49 nm (ARILMO) was prepared by a delamination/reassembling process. The obtained ARILMO sample was characterized by XRD, DSC-TGA, SEM, IR and elemental analysis. Experimental results indicated that the intercalated type and the amount of arginine molecules were connected with the pH values of the arginine solutions, and the intercalated amount of arginine molecules was 1.80 mmol/g.

Key words: layered manganese oxide, intercalation arginine, delamination/reassembling, nanocomposite
