Síntese e propriedades catalíticas em reações de oxidação de goethitas contendo nióbio Synthesis and catalytic properties on oxidation reaction of goethite containing niobium

<abstract language="eng">Nb-substituted goethites have been prepared and characterized by Mössbauer spectroscopy, XRD, SEM and BET surface area measurements. Mössbauer and XRD analyses suggested that Nb replaces Fe3+ in the structure with duplet formation. The insertion of Nb into th...
