Embodiment 1
[0024] The preparation method of the iron oxide nanowire of the present embodiment comprises the following steps:
[0025] 1) Mix 300ml oleylamine with 25g ferric oleate to obtain a mixture;
[0026] 2) Under stirring conditions, heat the mixed solution obtained in step 1) to 150°C, keep it warm for 1 hour, remove the moisture contained in the system, then rapidly heat it to 210°C, and react at constant temperature for 12 hours to obtain the reaction product;
[0027] 3) Cool the reaction product to room temperature, add an equal volume of acetone, and centrifuge to obtain a black precipitate;
[0028] 4) The obtained black precipitate was vacuum-dried at 60° C. for 12 hours, and the obtained black powder was the iron oxide nanowire.
Embodiment 2
