comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولComparison of Catalytic Activities for Sonocatalytic, Photocatalytic and Sonophotocatalytic Degradation of Methylene Blue in the Presence of Magnetic Fe3O4/CuO/ZnO Nanocomposites
Fe3O4/CuO/ZnO nanocomposites with different molar ratio were synthesized using sol-gel method. The as-synthesized samples were characterized by X-ray diffraction (XRD), UVvisible spectroscopy, BET surface area analyszer, and Electron Spin Resonance (ESR). The sonocatalytic-photocatalytic-sonophotocatalytic activity of as-synthesized samples was investigated based on methylene blue degradation. ...

15 صفحه اولMethylene Blue and Phenol Photocatalytic Degradation on Nanoparticles of Anatase TiO2
A photocatalyst was obtained by treating the commercial amorphous anatase titanium dioxide with ammonia water. During the preparation of photocatalytic material the optimal conditions of the separation operation were found. The photocatalyst was characterized by UV/VIS-DR, FTIR-DR, and XRD techniques, and high-resolution transmission electron microscopy (HR-TEM). According to the XRD method, th...
