Effect of surfactants on the size and shape of cobalt nanoparticles synthesized by thermal decomposition
H Shao, Y Huang, HS Lee, YJ Suh… - Journal of applied physics, 2006 - pubs.aip.org
Cobalt nanoparticles with various morphologies were synthesized by thermal decomposition
of cobalt acetate in the presence of various surfactants at 260 C. A combination of
surfactants consisting of sufficient amount of oleic acid together with polyvinylpyrrolidone
and oleylamine resulted in well-dispersed cubic cobalt nanoparticles of∼ 25 nm in average
size. When 1, 2-dodecanediol was added as a reducing agent to the surfactant mixture,
triangular-prism-shaped nanoparticles of∼ 50 nm in average size were synthesized …
