Supercritical water synthesis and deposition of iron
oxide (α-Fe2O3) nanoparticles in activated carbon
Iron oxide (α-Fe2O3) nanoparticles were deposited on the
surface and in the pores of
activated carbon
supplieractivated carbon pellets using
supercritical water to synthesize the particles from a
precursor solution of ferric nitrate. The dispersion of
the particles in the activated carbon was found to depend
mainly on the immersion time in the precursor solution at
room temperature. Two types of dispersions were obtained:
egg-shell dispersions at low immersion times and uniform
dispersions at high immersion times. The particle size
and size distribution, on the other hand, were influenced
mostly by precursor concentration. Although the catalytic
properties of the α-Fe2O3 in AC composites were not
evaluated, the procedure of employing supercritical water
to deposit metal oxide particles on hydrophobic surfaces
inside support structures offers promise for carbon-
supported catalyst preparation without the use of toxic
or noxious solvents.
