| 摘 要： | 采用嵌段聚合物P123为表面活性剂,以氯化铝和氯化钴为无机先驱物,采用溶胶-凝胶法合成介孔铝酸钴纳米粒子。X射线衍射(XRD)表明样品具有单一的尖晶石型结构,利用氮气吸附-脱附比表面测定仪测得不同焙烧温度样品的比表面积,发现700℃焙烧的样品比表面积最大,其比表面积为59.3m2/g,孔径为10.8nm。紫外可见光谱仪测示表明纳米铝酸钴样品为明亮的蓝色,在545nm、585nm和625nm处有三重吸收峰。

| Abstract: | Mesoporous cobalt aluminate spinel has been successfully synthesized by using aluminum nitrate chloride and cobalt chloride as the inorganic precursors,triblock copolymer Pluronic P123 as the structure-directing agents,through the sol-gel method.X-ray diffraction(XRD) pattern shows that the sample is single-phase cubic material with the spinel-type structure.The specific surface area is determined by nitrogen adsorption-desorption measurement,the result show that the surface area and pore size are 59.3m2/g and 10.8nm,respectively.The cobalt aluminate nano particle display bright blue color with a triple absorption peak around 545nm,585nm and 625nm by UV-vi-sible spectrometer. |
