Abstract
Nanosized rod-type ferric oxyhydroxide particles were prepared by forced hydrolysis in the presence of cetyltrimethyl ammonium bromide (CTAB). Selective adsorption of CTAB on the surface of particles induces the anisotropic growth of the particles. The resulting particles were characterized using XRD, TEM, SEM, TG-DTA and BET.

Keywords: iron oxide; forced hydrolysis; morphology; CTAB; surfactant
