e/Incipient Wetness Impregnation

Information
has gloss	eng: Incipient wetness impregnation (IW or IWI) is a commonly used technique for the synthesis of heterogeneous catalysts. Typically, the active metal precursor is dissolved in an aqueous or organic solution. Then the metal-containing solution is added to a catalyst support containing the same pore volume as the volume of solution that was added. Capillary action draws the solution into the pores. The catalyst can then be dried and calcined to drive off the volatile components within the solution, depositing the metal on the catalyst surface.The maximum loading is limited by the solubility of the precursor in the solution. the concentration profile of the impregnated compound depends in the mass transfer conditions within the pores during impregnation and drying.
