Resumen:
Pure (KNbO3) and titanium-substituted (KTi0.1Nb0.9O3 and KTi0.2Nb0.8O3) potassium niobates with perovskitecrystalline structures were prepared, characterized and tested as catalysts in the selective oxidation of 2-(methylthio)benzothiazole to its corresponding sulfoxide and sulfone. These catalysts,which have not previouslybeen reported for organic sulfide remediation, are the most active catalysts among those discovered to date forthis type of oxidation reaction. Hydrogen peroxide was employed as the oxidant, and the reaction parameterswere tested in order to find milder reaction conditions.
