Hollow magnetite microspheres have been synthesized by a simple process through a template-free hydrothermal approach. Hollow microspheres were surface modified by coating with a silica nanolayer. Pristine and modified hollow microparticles were characterized by field-emission electron microscopy, transmission electron microscopy, X-ray diffraction, X-ray(More)
The photocatalytic degradation of p-aminobenzoic acid was studied using TiO2 nanowires as the catalyst synthesized through a hydrothermal procedure. The as-synthesized TiO2 nanowires were fully characterized by SEM, TEM, XRD and Raman with a very high surface area of 512 m(2) g(-1). The photocatalytic degradation of p-aminobenzoic acid was carried out under(More)
Was studied the liquid-phase paranitrophenol (PNP) dynamic adsorption in a packed bed adsorption reactor (PBAR), filled with dealuminated Y zeolite (DAY) and granulated active carbon (GAC). In addition, was measured the equilibrium maximum amount of adsorption for the system: PNP aqueous solution-DAY zeolite, at 300 K, to compare it with other adsorbents.(More)
