Nióbia sintética modificada como catalisador na oxidação de corante orgânico: utilização de H2O2 e O2 atmosférico como oxidantes Modified synthetic niobia as catalyst in the oxidation of organic dye: utilization of H2O2 and atmospheric O2 as oxidants

<abstract language="eng">In this work synthetic niobia was used to promote the oxidation of methylene blue dye in aqueous medium. The niobia was characterized by N2 adsorption/desorption, XRD and TG measurements. The presence of reactive species on the niobia surface strongly increas...
