WebNi, Cu, Pt, Co, and Ga were added via incipient wetness impregnation. Metal nitrate hydrates were used as precursors for all metals except Pt, which required H 2 PtCl 6-6H 2 O as a precursor. Metals were introduced to the support at constant molar ratio of 1:2 metal-to-aluminum. After impregnation, the catalysts were dried in an oven at 110 °C Web1) Incipient wetness impregnation of Na-Y zeolite . Copper (II) exchanged Na-Y zeolites (Cu/Y-IM) were . prepared. with different percentages of Cu loading (2.3 wt. % and 5.5wt. % by an incipient wetness impregnation method. It . is necessary to keep the zeolite carrier completely wetted. Aqueous solution of metal-nitrate was added dropwise to the

WebIncipient wetness impregnation is also called the dry impregnation method to fabricate heterogeneous catalysts. Typically, the metal precursor is dissolved in an organic solution. In this process, the metal is introduced to the catalyst support, then the capillary action causes absorption of the solution into the pores. WebThe incipient wetness impregnation of S3 composite with a basic solution results in strong textural and morphological modifications (Table 1, composites S4).One of the effect is the first decrease of the specific surface area of the composite after basic impregnation at pH = 10.5 (S4i10.5), followed by an increase in specific surface area for the basic impregnation … poor traction meaning
