Na型层状锰氧化物于0.1mol/LHCl溶液中离子交换制得前驱体H型层状锰氧化物.H型层状锰氧化物在十二胺乙醇溶液中反应得到层间距为2.62nm的中间产物——十二胺插入的层状锰氧化物,该中间产物在异丙醇钛和乙醇的混合溶液中溶剂热处理得到层间距为1.24nm的钛酸柱撑层状锰氧化物.在300℃条件下经2h焙烧得到二氧化钛铸型氧化锰微孔材料.应用XRD,DSC-TGA,SEM,TEM,IR,氮气吸附实验及元素分析进行了不同阶段所得试样的分析表征.结果表明十二胺分子在锰氧层间的最大插入量为2.2mmol/g,异丙醇钛分子的置换插入生成了组成为Mn7.00Ti1.74O23.3(C12H25NH2)0.52?1.93H2O的铸型层状锰氧化物.300℃焙烧处理所得二氧化钛铸型氧化锰微孔材料的比表面积为140m2/g.
Na-type layered manganese oxide ion exchange in 0.1mol / LHCl solution obtained precursor H-type layered manganese oxide.H-type layered manganese oxide in dodecylamine ethanol solution was obtained at a layer spacing of 2.62nm Intermediate product-dodecylamine inserted layered manganese oxide, which was solvothermally treated in a mixed solution of titanium isopropoxide and ethanol to obtain a titanate titanate layered manganese oxide layer spacing of 1.24nm at 300 ℃, calcined at 2 ℃ for 2h to obtain TiO2 microporous manganese dioxide microporous material. The samples were characterized by XRD, DSC-TGA, SEM, TEM, IR, nitrogen adsorption and elemental analysis. The results showed that twelve The maximum insertion amount of amine molecules between manganese oxygen layers is 2.2mmol / g, the substitutional insertion of titanium isopropoxide molecules produces a layered manganese oxide with Mn7.00Ti1.74O23.3 (C12H25NH2) 0.52? 1.93H2O The specific surface area of the titania-cast manganese oxide microporous material obtained by calcination at 300 ℃ was 140m2 / g.
