Influence of the Active Phase (Fe, Ni, and Ni–Fe) of Mixed Oxides in CWAO of Crystal Violet

Abstract: The catalytic oxidation of aqueous crystal violet (CV) solutions was investigated using Ni and Fe catalysts supported over Mg–Al oxides synthesized by the autocombustion method. The influence of temperature, loading, and selectivity were studied in the catalytic wet air oxidation (CWAO) of CV. The kind of metal had an important contribution in the redox process as significant differences were observed between Fe, Ni, and their mixtures. The catalysts with only Fe as active phase were more efficient for the oxi… Show more

“…El desplazamiento a temperaturas de reducción (curvas II-IV) más bajas, así como la formación de partículas de NiO pequeñas y dispersas (curva I) nos sugiere que con la incorporación de Fe se tiene una mejor dispersión de las fases de Ni presentes en el catalizador [60,65] .…”
