摘要：

Nanosized cobalt aluminate (CoAl2O4) spinel powders have been prepared by a hydrothermal method. Titration of Co-Al mixed solution by NaOH solution yields a precursor with crystalline Co-Al-layered double hydroxide (LDH) and bayerite aluminum hydroxide (beta-Al(OH)(3)) phases. After the precursor is hydrothermally reacted at 245 degreesC for 20 h, CoAl2O4 powders with a size of 65-75 nm and with a surface area of about 32.3 m(2)/g are prepared. The formation process has been investigated by X-ray diffraction (XRD), FT-IR, BET surface area measurement, and transmission electron microscopy (TEM) techniques. (C) 2003 Elsevier B.V.
