Several factors determine the optimal metal loading for a given catalytic process:
1. Type of Reaction: Different reactions require different metal loadings for optimal performance. 2. Nature of Metal: Precious metals like platinum and palladium require lower loadings compared to base metals. 3. Support Material: The interaction between the metal and the support material affects the dispersion and availability of active sites. 4. Operating Conditions: Temperature, pressure, and reactant concentration can influence the effectiveness of the metal loading.
