Method of manufacturing ferrous oxide nanoparticle, method of forming carbon nanotube, and ferrous oxide nanoparticle

摘要

A method of manufacturing a ferrous oxide nanoparticle (100, 1200) includes a water removing step (S202, S1102) of raising the temperature of a solution containing an iron oxide (211), an organic acid (212) dissolving the iron oxide (211), and a first solvent (213) to a first temperature and removing water in the solution, a second temperature maintaining step (S203, S1103, S1105) of raising the first temperature to a second temperature and maintaining the second temperature, and a particle extracting step (S204, S1106) of extracting the ferrous oxide nanoparticle (100, 1200) from the solution after the second temperature maintaining step (S203, S1103, S1105).
