Abstract
These nanocrystalline ferrihydrite-goethite precipitates are of a relatively high chemical purity (3% SiO2, Zn 1300 ppm, trace and rare earth elements <100 ppm) and thus applicable in various nanotechnologies. With a surface area of 270 m2 g-1, precipitate possesses a high catalytic activity in the decomposition of hydrogen peroxide, which is comparable with that found for commercially accessible FeO(OH) catalyst. Another superior aspect of such natural nanoparticles presents a cheap and suitable precursor for a thermally induced solid-state synthesis of the stable core-shell R-Fe- FeO nanoparticles that are well applicable in reductive technologies of groundwater treatment. Just the possibility of using the undesirable waste contaminating the environment in further environmental technologies is the key practical benefit discussed in this paper.
