以六水合氯化镁(MgCl2·6H2O)为镁源,水合肼(N2H4·2H2O)为沉淀剂,采用化学共沉淀法制备纳米氢氧化镁前驱体煅烧得到分散性良好的不同纳米结构的氧化镁(MgO)纳米片.通过XRD、SEM、TEM对产物的结构和形貌进行分析,初步研究了反应温度和时间对MgO纳米片的形貌和结构影响,分析了MgO多孔纳米片的生长机理.结果表明:25℃,24h下MgO纳米片大小均一尺寸在20～40 nm；当温度升高到100℃,72 h生长的多孔MgO纳米片缺陷多,是晶粒相互连接起来的,纳米孔洞在10 nm；140℃72 h制备的多孔纳米片尺寸均一在100～200nm.因此可以通过调节反应温度和时间来控制多孔氧化镁纳米片结构.
