On the nature of goethite, Mn-goethite and Co-goethite as supports for gold nanoparticles
(Elsevier Science Sa, 2008-06)
Mn- and Co-substituted goethite (α-MnFeOOH and α-CoFeOOH) and pure goethite (α-FeOOH) were studied as supports for gold catalysts. The textural properties of these solids were studied by N2/77 K adsorption. Mn and Co ...
Structure and reactivity of synthetic Co-substituted goethites
(Mineralogical Society of America, 2008-04)
A set of synthetic goethites were prepared from Fe3+- and Co2+-nitrate solutions in alkaline media with a Co/(Co + Fe) ratio (xCo) up to 10 mol%. The structural characterization of the resultant solid phases was carried ...
Structural study of a series of synthetic goethites obtained in aqueous solutions containing cadmium(II) ions
(J C P D S-int Centre Diffraction Data, 2003-03-01)
The capacity of goethite for Cd-II substitution has been explored in a series of synthetic samples prepared from Fe-III and Cd-II nitrate solutions aged 21 days in alkaline media. The total metal content ([ Fe] + [ Cd]) ...

Heterogeneous photo-Fenton process mediated by Sn-substituted goethites with altered OH-surface density
(Elsevier Science SA, 2019-08)
Heterogeneous photo-Fenton process using several pure- and Sn-incorporated goethites was investigated for the decolourisation of methyl orange (MO). The used goethites presented a partial Sn(IV)-for-Fe(III)substitution. ...
LDA+U and GGA+U studies of Al-rich and bulk goethite (α-FeOOH)
(Elsevier, 2013-01-15)
The electronic and structural properties of bulk goethite and Al-rich goethite were studied on the basis of spin-polarized DFT at the LDA+U and GGA(PW91)+U levels. Firstly, the periodic model of bulk goethite was ...
Enhanced As (V) Adsorption Properties in Sn-Substituted Goethites - Changes in Chemical Reactivity and Surface Characteristics
(International Journal of Innovative Research in Engineering & Management, 2015-11)
In this work, the adsorption of arsenic (V) onto crystalline substituted goethites was studied for samples with different Sn- contents. The highest Sn-content of the prepared samples was 5.5 (expressed as 100?[Sn]/[Sn]+[Fe]) ...
Chemical, structural and hyperfine characterization of goethites with simultaneous incorporation of manganese, cobalt and aluminum ions
(Elsevier Science, 2015-10)
To elucidate the influence of bi-substitution on the structural and hyperfine properties of goetites, two series of (Al,Co)- and (Mn,Co)-substituted goethites were synthesized in alkaline media by aging several ferrihydrites ...
