The metal-support interaction via Rh O P bonding in the catalyst prepared using arc-plasma was found to be weaker than in the catalyst prepared by conventional wet impregnation.
Fe Co/CaCO3 catalyst/support was prepared by wet impregnation method.
The catalysts were prepared by a wet impregnation method.
Impregnation = W impregnated - W dry W dry × 100 (3).
This finding indicates that upon impregnation process Co2+-alumina interaction is weaker than Mo6+ alumina interaction, owing to the favorable electrostatic interaction of Mo6+ citrate species with alumina surface.
He also impregnates her, or supports her impregnation, or something.
"Dry" impregnation is employed in the case of weak adsorption strength, using a sufficient volume of precursor solution to fill the total pores of the carrier batch.
After the impregnation of element Ga, zeolite acid sites appeared to be weaker than parent zeolite, and only weak acid sites existed [17].
In comparison with catalysts prepared by impregnation, more cobalt ions entered into CeO2 lattice, and resulted in weaker interaction between active phase and ceria on surface of Co3O4/CeO2 prepared by co-precipitation.
First, the improved sugar release is connected to the natural long term impregnation of organic acids on the biomass where the lignocellulosic structure is loosened by weak acid hydrolysis accomplished by organic acids [ 6].
