How do reaction conditions influence catalyst selection?
Reaction conditions such as temperature, pressure, and the nature of the reactants play a significant role in catalyst selection. For example:
Temperature: Some catalysts are only active at specific temperature ranges. High temperatures may require more robust materials, while low temperatures may need catalysts with high intrinsic activity. Pressure: Catalysts used in high-pressure processes must withstand mechanical stress. Gas-phase reactions often require different catalysts than liquid-phase reactions. Reactant Nature: Catalysts must be compatible with the chemical nature of the reactants. For instance, acid or base catalysis may be necessary for certain types of reactions.
