There are several methods for preparing supported catalysts:
Impregnation: The carrier is soaked in a solution containing the catalyst precursor, followed by drying and calcination. Co-precipitation: The catalyst and carrier materials are co-precipitated from a solution, followed by filtration, drying, and calcination. Deposition-Precipitation: The catalyst precursor is precipitated onto the surface of the carrier from a solution. Sol-Gel Method: A sol containing the catalyst and carrier precursors is gelled, dried, and calcined.
