چکیده
|
Highly meso-porous pt contained γ-al2o3 nanostructure was prepared by a combined sol gel-pyrolysis method in the presence of polyvinylpyrrolidone and pluronic p123 as surfactant. the surface of the prepared nanostructure was decorated with 1-butyl-3-methylimidazolium hexafluorophosphate ([bmm]pf6) ionic liquid to enhance the sorption capacity and prevent the poisoning of the catalytic active sites. the catalyst was characterized by x-ray diffraction powder (xrd), transmission electron microscopy (tem), energy dispersive x-ray (edx), and brunauer–emmett–teller surface analysis (bet) methods. the xrd pattern and the results of elemental analysis well confirmed the crystalline phase of gamma-alumina and the presence of pt nanoparticles on the surface. decolorization of anazolene sodium (as) dye compound as a typical wastewater was carried out using h2o2 as oxidative agent and the results showed that the prepared nanostructure had promising catalytic activity. the results of the recycling experiments showed that [bmim]pf6/pt/γ-al2o3 is more promising than pt/γ-al2o3 which points out the role of ionic liquid layer on the surface.
