Several factors can influence the effectiveness of impregnation:
- Pore Structure: The pore size and distribution of the support material can affect how well the metal species are distributed. - Solution Concentration: The concentration of the metal precursor can determine the amount of metal loaded onto the support. - pH and Temperature: The pH and temperature of the impregnation solution can affect the interaction between the metal precursor and the support. - Drying and Calcination: Post-impregnation drying and calcination conditions can influence the final dispersion and oxidation state of the metal species.
