Abstract

Abstract: The powders of one dimensional nanostructures of Co₃O₄ were synthesized hydrothermally followed by decomposition of the precursors in the Co(NO₃)₂-CO^2-₃ system. The aspect ratio of products could be controlled by tailoring the concentration of Co(NO₃)₂ aqueous solution. That urine and hexamethylenetetramine taking the place of sodium carbonate as the precipitants could also produce 1D Co₃O₄ showed lights on understanding the mechanism of formation of 1D structures. The existence of CO^2-₃ intercalated between the brucite layers played an important role in the formation of 1D structures.
