摘要
本文利用XRD,SEM,DTA及BET等现代仪器,研究了K-Zn-Ti层状金属氧化物(LMO)经HAC,NH4Cl交换前后的基本性能。结果表明:该LMO具有良好的离子交换性能,其面网间距由0.78nm分别增加到0.86nm和0.88nm.同时,比表面积由27m2/g分别增加到30m2/g和59m2/g,可望作为大孔分子筛的制备原料。
K-Zn-Ti layered metal oxide (LMO) is exchanged with acetic acid and ammonium chloride aqueous solution. XRD, SEM. DTA and BET techniques are used for. characterization of its basic property. It is shown that. K-Zn-Ti (LMO) possesses better ion-exchange property. After being exchanged with acetic acid and ammonium chloride. its interlayer distance (d value) increases to 0.86 nm and 0. 88 nm from 0. 78 nm, and its specific surface area increases to 30m2/g and 59m2/g from 27 m2/g respectively.
