镁铝层状双金属氢氧化物的制备及表征OA北大核心CSTPCD
Synthesis and Characterization of Mg-Al Layered Double Hydroxides
分别以氨水和氢氧化钠为沉淀剂,采用共沉淀法合成Mg-Al层状双金属氢氧化物,对产物的晶相、形貌和结构进行表征,采用正交实验法研究金属离子比例、反应温度、pH值等因素对产物层间距及层板生长机制的影响.结果表明,以氨水作为沉淀剂,Mg与Al物质的量比为2∶1,pH值为9.5,反应温度为40℃时,得到结晶度高,物相纯净且层间距d003)达0.882 1 nm的层状双金属氢氧化物.
The Mg -Al layered double hydroxides were prepared by co-precipitation method using sodium hydroxide (NaOH) and ammonia as precipitant. The structure and morphology of products were characterized. The main factors related to interlamellar spacing and growth mechanism of Mg-Al layered double hydrosides were researched by orthogonal tests. The results show that when ammonia is used as precipitating agent, the molar ratio of Mg and Al is 2:1, pH is 9.5 and the…查看全部>>
