The structure and magnetic properties of Co-containing zeolites prepared by wet impregnation were investigated. The samples were calcined and then reduced in flowing H2. The samples studied have large saturation magnetization ...

Magnetic MCM-41 type mesoporous silica materials were synthetized and modified with different iron loadings by the wet impregnation method. The evolution of iron speciation, depending on the metal loading and associated ...

Potassium and acid ferrierites were impregnated with boron species by wet and incipient wetness techniques. All samples display a medium-intensity band at 3,450-3,470 cm-1 associated to Si-OH•••O groups corresponding to ...

In this work, Ag and Ni metals incorporation effect on the water adsorption and physicochemical properties of 5A zeolite was studied. For that, Ag/5A and Ni/5A zeolites with different amounts of metal (4, 10 and 20 wt%) ...

MCM-41 structures were synthesized and modified by direct (one-step) incorporation (DI) and wet impregnation (WI) methods. The solids were characterized by XRF, XRD, N2 adsorption and UV-Vis DR, and catalytically evaluated ...

Catalysts of Pd-In supported on activated carbon fiber were synthesized, characterized, and evaluated for the removal of nitrogen oxyanions from water. The work was carried out aiming the development of a green synthesis ...

The impregnation of boron species on ferrierite in the acid form promotes the catalytic activity in the linear butene skeletal isomerization reaction. Nevertheless, more important is that the presence of boron on potassium ...

MgAl2O4 spinel employed as support of reforming catalysts was doped by CeO2. The samples were prepared by wet impregnation from aqueous solutions of cerium nitrate, with and without chelating agents. The chelating agents ...

Pt/KL catalysts are highly active and selective for the aromatization of hexane, but they display a very high sensitivity to even small concentrations of sulfur in the feed. Tm-containing Pt/KL catalysts were prepared by ...
