Incipient wetness 含浸

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 Incipient wetness impregnation (IW or IWI), also called capillary impregnation or dry impregnation, is a commonly used technique for the synthesis of heterogeneous catalysts. Typically, the active metal precursor is dissolved in an aqueous or organic solution.
