There are several methods to achieve dilution in catalysis:
Physical Mixing: This involves blending the catalyst with an inert material such as silica, alumina, or another suitable support material. This method is commonly used in heterogeneous catalysis. Solution Dilution: In homogeneous catalysis, the catalyst can be diluted by dissolving it in a solvent. The concentration can be controlled by adjusting the volume of the solvent. Impregnation Techniques: This involves impregnating a support material with a dilute solution of the catalyst precursor, followed by drying and activation. This method is used to achieve uniform dispersion of the catalyst on the support.
