Several factors can influence the shape and nature of catalyst loading curves, including:
1. Catalyst Activity: Highly active catalysts may reach saturation at lower loadings. 2. Substrate Concentration: The concentration of reactants can affect how quickly the reaction rate plateaus. 3. Reaction Conditions: Temperature, pressure, and solvent can all impact the effectiveness of the catalyst. 4. Deactivation: Catalyst deactivation over time can alter the expected loading curve.
