Debido a la creciente industrialización a nivel mundial, se ha tenido un aumento significativo en la cantidad de residuos generados, la gran mayoría de ellos catalogados como peligrosos por su alta toxicidad para diferentes organismos y ecosistemas. De ésta problemática surge una adicional y es la relacionada con su tratamiento, ya que en...

Crystalline orthorhombic Bi2WO6 powders were synthesized by a hydrothermal method from aqueous solutions of Bi(NO3)3 5H2O and Na2WO4 2H2O over a range of three selected pH values (2.0, 5.0 and 7.0), using NaOH as precipitating agent. The as-prepared catalysts were char- acterized by XRD, BET, FE-SEM, TEM, XPS and UV-vis spectroscopy. The effect...

Mixed oxides, α-Fe2O3/Bi2WO6, were prepared using a mechanical mixing procedure by adding to the Bi2WO6 previously obtained by hydrothermal method the corresponding amount of a prepared α-Fe2O3, the latter obtained by thermal decomposition of Fe(NO3)∙9H2O. The physicochemical surface, structural, morphological characteristics and optical...

For this present work, a series of Au-metallized TiO 2 catalysts were synthesized and characterized in order to compare their performance in two different catalytic environments: the phenol degradation that occurs during the liquid phase and in the CO oxidation phase, which proceeds the gas phase. The obtained materials were analyzed by...

Different composites based on ZnO/Ag3 PO4 and ZnO–malachite (Cu2 (OH)2 CO3 ) were synthesized in order to determine their effectiveness in the treatment of municipal and industrial wastewaters (mainly polluted by enteropathogenic bacteria, dyes, and heavy metals). The addition of Ag3 PO4 and malachite did not significantly modify the...
